I agree.  I think a useful first step could be to teach frameset to
restore windows, but not frames, in some useful way (e.g., restore the
window configuration of just a single frame).

Alternatively, we could try teaching desktop.el to better filter the
frame parameters so that it could ignore the problematic ones, but I
think this will be harder and less reliable.

I wouldn't.  It looks too ad-hoc to me, and its only purpose is to fix
desktop.el, so why does it need to be in frameset.el?

The display-graphic-p condition was introduced because we had bug
reports about the previous behavior (which didn't disallow restoring
framesets in -nw sessions).
