As long as the users are not allowed to write TEXMFSYSVAR, that will
work just fine.

I do not get it: you have write access to TEXMFSYSVAR, so you (for all 
intents) actually are the administrator / system maintainer. How is that
any different from the installer usage, from a program's point of view?

In other words: if you do not want normal users' programs to put stuff
in TEXMFSYSVAR, why do you allow write access to TEXMFSYSVAR to normal
users?  That is a contradiction that to me sounds like a configuration
error.
