Suppossing that it is expected to be defined on the Emacs sources, a
symbol might be absent from your install either because it is too old
(the symbol was introduced on a more recent Emacs version) or too new
(the symbol was removed from the Emacs sources). The later case is not
very frequent because the Emacs maintainers are very conservative when
removing old stuff.

This is the slowest resource, yes.

Personally I do 2 before 1, using the Changelog files, the NEWS files
and the version control history.
