You can't just flip from python2 to 3 and back without other
mumbo-jumbo.  Gentoo started to kill off python2 recently.  They are
finding a ton of stuff that is not python3 ready, in core stuff that has
not been patched in nearly a decade.  Big mess.

I know what it does, muck with libraries, but gpsd does not use it.
It used to be popular.

Nope, that is why it is not on by default.  And gone now, repalced
by a runtime option "--speed XXX".

Pretty common useage.

Not part of gpsd, so not on topic here.  Yet another unneeded
software layer to break.

So roll it back, and change incrementally.

Don't care, not part of gpsd.
