You can theoretically build a users/groups permissions scheme using the 
user_rights and cur_restrictions fields (both are comma-separated sets 
of text tokens and can be fairly arbitrarily extended), but as you 
noticed this isn't supported by the current code which is hard-coded and 
special-cased for a few values.

If you want to try this, start by rewriting Title::userCanEdit() and 
Title::userCanRead(), which control write and read access to given 
pages. You'd also need to add a more intelligent way to assign page 
permissions & user privileges.

Honestly, I'd recommend you just give all your users read/write 
permission to all pages... If they change things they're not supposed to 
it's recorded in the audit trail and incorrect changes can be easily 
reverted.
