My understanding of
https://lists.gnu.org/archive/html/emacs-devel/2015-12/msg00309.html is
that the goal is to make Emacs builds fully deterministic (even by default,
or as the only option). According to
https://reproducible-builds.org/docs/timestamps/ it would be great to avoid
timestamps in loaddef files (and everywhere else) entirely.
