Yes, GUD's support for particular debuggers should be made more modular.
It should also be possible to have several GUD sessions using different
debuggers at the same time.

Patches welcome.

I think a good first step would be to kill gud-def.
Instead of gud sub-modes using

  (gud-def gud-break "break %f:%l"  "\C-b" "Set breakpoint at current line.")

in their main function, we could have a top-level (for example)

  (define-gud-cmd gud-break "\C-b" "Set breakpoint at current line.")

and then the gud sub-mode would only do something like

  (set (make-local-variable 'gud-break-cmd) "break %f:%l")

so the global menu could use
  :visible gud-break-cmd
instead of
  :visible (memq gud-minor-mode '(gdbmi gdb dbx jdb))

Of course, maybe this is not the best idea.  I'm also thinking that some
each gud sub-mode should be defined as a major mode that derives from
gud-mode.
