There was this thread:

I somewhat recall looking into removing some of this code (I don't
remember if it was mdebugread or something else) and finding to my
dismay that it was intertwined with other somewhat more living code in a
way that made it hard to untangle. I thought I sent a note about this,
but I can't find it now.

I'm generally in favor of removing things. gdb has too much moribund
code. However it's not always easy to tell what is really dying, and
one is less likely to get complaints about a patch than a removal.
Perhaps at some point we can say it is either definitively dead or
definitively broken (like the solib-sunos stuff last year) and then
remove it.
