Yep.  And every now and then I double check to see if it has changed
and I somehow missed learning about it.

I'm proud to be a GNU developer.  I've been using and modifying GNU
tools for over 20 years (uh, oh, did I just date myself?).

Did Sun make any effort pull together a list of stab extensions and
document the result?  I wasn't aware of such an effort.

Sun may have had the master copy at one time, but I would tend to
think that their copy is no longer the master copy.  I would argue
that they lost mastership through inaction.  Several companies made
extensions to stabs.  Did Sun make any effort to keep them compatible?
Even just acting as a ``registry''?  I wasn't aware of such an effort.
I know that when stabs.texinfo was created (by John Gilmore at Cygnus)
some reverse engineering of the stabs created by various compilers
