On a lot of devices, the "power button" is the resume button. When you
"turn it off" it suspends, and when you "turn it on" it resumes.

I realise that. I do work on embedded devices, and this behaviour is
explicitly there to support embedded devices.
I've suggested a workable solution to you which allows both of us to
have the behaviour we both desire from the system. That sounds like
