Absolutely!  I'm fighting that on a system which, after an update,
insists on opening new terminal windows centered - some recent policy
change is now doing that instead of where the same thing was placed the
last time it was open (I assume I'll find the knob for that eventually).
 As others have said, there's no one-size-fits-all; on a big screen you
certainly don't want the same things as on a phone, where "take over the
whole screen" might indeed be the only thing that makes sense.
