The first report appear to be from Frank Schmitt after which I added the
alias.  I heard no more so presumed that fixed the problem.

I don't know what a "resizing echo area" is, but is it always a problem?
Does it stop Semantic from working?

I would guess that the next release of Semantic will be before the next
release of Emacs.  Has anyone reported this as a bug there?

No, not really.  The user experience is pretty much the same.

I explained why earlier, and in the thread(s) about this change.  GUD is not
special and those involved were agreeable to the changes.  I suggest that you
read that material.
