you are correct that we won't have control over every hardware button on any 
device, but the power button is exceptionally common (in fact, i don't know a 
tablet device doesn't have one and i now own 4 different tablets and have 
examined at least a dozen others). home, back, etc. are not guaranteed but we 
can rely on the power button.

also, every device we currently support has the power button we need. so we're 
designing for a possibility that we currently don't have any examples of :)

the original reasons for the software power button was:

* the power management configuration was not reliable, and this was a work 
around.

* a way to sleep vs shutdown vs lock was desired and this was the quick fix

having an implicit "will sleep in N seconds" upon lock that can be cancelled 
along with the power profile configuration working makes those points moot.

the suggestion is to automatically start a sleep unless stopped manually (e.g. 
by pulling an element across the screen). "lock but don't sleep" is just not a 
common use case with tablets. this approach prioritizes the common use case 
(sleep) while accomodating the use use case for "just lock, don't sleep".

yes, this is a hardware feature ...

unless we are doing session management and/or you have unsaved work somewhere, 
this shouldn't matter much for these sorts of devices.
