Nope. But we can't do the job of a person running a shared hosting
webserver, anyway, because the security issues in that area of business
are so intense that people doing shared hosting for random crap code of
their customers need to review and overhaul the default configuration in
minute detail anyway.

Again, if there's something we can do to make their jobs easier without
impacting a significant amount of our other users, I'm all for it. I
don't think this particular bit qualifies, however.

Yes, you (a person who maintains servers in a shared hosting business)
need to do that. We (Debian) have different priorities, however.
