So are you saying that adding Python will enable features that are
beyond user-defined commands (a.k.a. scripting)?  If so, what are
those features?

I have no objections to renaming that chapter.

The chapter name doesn't say "GDB Commands", it says just "Commands".
But let's not argue about that on which we agree ;-)

Maybe I'm missing something, because I don't see how this is different
from what we have now.  For example, the .gdbinit file distributed
with Emacs already pretty-prints Emacs Lisp data types, as do the
various GDB extensions for printing Qt data types that float around.
They are all written in the current scripting CLI language.  How will
Python be different in this department?
