It's complicated in your opinion, and I may agree with that, but it's no
more complicated then, say, a situation where you have two windows, but
one of them is dedicated, and you do, say, describe-symbol, or something
else that pops a window.  Which is just what happens in xref.el: the
starting window where you invoked C-x 4 . behaves like it it is
temporarily dedicated to its buffer.

"Superior" in UI is always relative.  I think the only way to know if to
test it for a while.  But to do that we have to close this bug first.

I didn't say we _can't_ have more discussion.  But let's first wrap up
this easy win by installing the patch that makes this configurable.

I'll test your last patch in a fresh Emacs to check if I can still
reproduce the problems I was finding the last time.  If I can't, I'll
just push it , unless someone objects.
