I can tell you that the Android port requires a complete screen redraw
on palette changes - ditto for anything else that doesn't support 8bit
palettes natively in hardware.

I think it comes down to what the alternative is.  If the entire
screen is changing anyway (eg: the DOTT swirly intro screen), then it
doesn't really matter whether you are using palette rotation or asking
the backend to update the entire screen some other way.  Palette
rotation to affect only a tiny portion of the screen would be
unfortunate.
