32-bit builds are almost dead, so you may want to revisit the default.
(See trend at https://debbugs.gnu.org/stats/emacs.html )

But isn't it about how much physical memory the system has?
Years ago people were saying 10MB was too small, eg
http://lists.gnu.org/archive/html/emacs-devel/2014-11/msg02358.html

Anyway, getting OT...

The largest el(c) file in the Emacs sources is ja-dic at 2.2MB,
well below the current default for large-file-warning-threshold.
So not warning about loading a 1/2GB file like in the initial report
seems like a disservice.
