Problem to solve
Some users can cause disruption by moving/renaming pages.
Social sanctions can keep them in check, but currently the only technical means to corral this type of behavior is a full site block, which is extreme for some situations.
Proposed solution
It would be useful to be able to *only* block users from moving/renaming pages on specific namespace.
In fact, this is very similar to T194529, But this task is limited to a specific namespace.
