Aha; I hope I understand correct:

Sysadmin can install packages for many users to share them, users have
read priviledge, not write of course. Sysadmin would install/uninstall
packages and a user would need to read autoloads.el from that shared
system dirctory, and then maybe even from it's own?

Could something like "site-autoloads.el" do? Similar to how
site-start.el works?

That file would be read only of course, and could be loaded before
user's autoloads are loaded. That way if user install same package but
different versions, user's would take precedence since it would override
site-autoloads. It would still be just two files to check for and
load. And hopefully path to it could be set in site-start.el or
elsewhere in setup so Emacs does not need to search entire load path to
find it?
