I have no control over "people", and little enough over XEmacs.
Better to spend the effort on having Emacs be smart about the info
files themselves, which either it can read or it doesn't matter, than
to have GNU and XEmacs.ORG try be anal about stuff that's not under
our control.  IMO.

That's fine, but I got the impression David was talking about the
specific dir file in the info directory where Emacs stuff resides.
What you're describing is just a "pre-caching" version of XEmacs's
current strategy.

AFAIK, install-info looks at @dircategory and @direntry.  Well, so
does XEmacs, and it gives them priority over dir.  The main issue here
is time spent in gunzip (and I'm not sure if that is anything but
process overhead, ie, with a zlib-capable Emacs this might go away),
otherwise it works well.
