Sorry I meant to write/ask this earlier but is there a reason for
choosing size vs mtime?
I guess the main reason is that the filesize() call is cached, and the
stat() call isnt. You do not want to do stat() calls on all included
files for every single page load. I suppose you could cache the stat
info yourself, but as Thomas said, in practice filesize() is good
enough.
