Any reason not to do this: brake hold then stop button
in order to put the car in park, I've been coming to a stop, applying brake hold, then hitting the stop button, and it automatically puts the car in park and shuts down -- any reason not to do this? is it not recommended?
thanks
thanks

I dont bother to apply brake hold. I just hit the start/stop button and open the door. It shuts down then shifts into park, which is reverse from what you posted. I also never use the parking brake unless I am parking on an incline.

The parking brake is there to protect the park pawl in the transmission. There is no reason not to use it every time you park.
You should put it on prior to putting the car into park - that little "bounce" the car gives against the driveline when it is not used puts unneeded stress on the park pawl, flex discs, and everything else.

In some countries where they do a very detailed car inspections it is important to use the parking brake as it really can get stuck by corrosion if not used especially in the areas where salt is used on roads in winter times.
I have used mine once when I parked in a steep incline.
And there is nothing that would be over stressed in the transmission system when not using the parking brake.

One of the jobs I put myself through college with was working in an automobile dealer service department. Broken parking pawls are not uncommon to see.

Yes, there is... the mechanical parking pawl (which is quite small, mind you...).

This was a Saturn dealer that I worked at. One of the more hilarious yet sad things I saw was this: A woman brought in a VUE because "park wasn't working". When she pulled into the service lane, she got out of her car and came in to sign in for her service appointment. Her car rolled backwards about 75 feet across the parking lot before reverse t-boning a brand new VUE.
When we asked her why she hadn't set the parking brake (knowing that park wasn't working at this point, as that is why she brought it in), she said she didn't know where it was (they have a handbrake lever). I had to excuse myself at that point...
I guess that hit it home for me to make it a habit.

Making it an automatic action is how I deal with it all. Kinda like putting on the seat belt, I just always do it.
(1) stop the car
(2) press the started/stop button, turning off the car (this leaves it in Neutral)
(3) stomp on the parking brake
(4) open door, which puts it into Park
And since the parking break is always on, I just always release it after starting the car.
My biggest problem is getting use to the audio system staying on until I open the door. I like it, though it just "feels wrong" ;-)

I have never used the parking brake in my entire life (probably a dumb idea) on any car and never had a problem, of course this will be the car that has the problem.
seems like after reading all this, i'd rather brake hold then hit the stop button to ensure the car is in park in case I decide not to get out right away.
When I first brought this heap home in sept 2013, my 3 year old was running behind the car after I had shut it off (he knows not to come by the car when it's on) and I hadn't hit the park button and I felt it creep backwards and slammed on the brakes (which at this point had lost that vacuum power) and panicked for a second before I realized I hadn't hit the button. The car was off so I didn't have camera or anything. hit the park button and the car stopped and all is well, but man.... I don't even want to go there.
completely my fault but it taught me to be extremely careful with this car's gear shifter.

I always put on the parking brake. Why? Mostly because my wife aways reminded me to do so if I didn't. 20+ years of habit...

I've noticed that when I come to a stop, do the brake hold, then hit STOP, the car rocks a bit before park is engaged automatically.
When I come to a stop, hit the park button, then turn the car off, no rocking or roll. I can see this rock & roll causing troubles downstream.
