Yes.

Only partially.  People who report backtraces seldom bother to start
GDB from the Emacs's src directory, let alone source .gdbinit by hand.
Moreover, latest versions of GDB refuse to auto-load .gdbinit files
from random directories, unless you put some magic in your ~/.gdbinit
(which most people don't).  Finally, this setting doesn't affect only
Lisp_Object, it affects any non-scalar arguments, so it has
non-trivial downsides of its own (which I guess is why it is not the
default).
