Admins and content moderators should be able to protect certain sections of a page instead of only being able to protect the entire page.
There's a page in a wiki I'm part of that has had edit warring in a certain section, however a different section of the same page is updated on a daily basis, usually by regular contributors. One solution that currently exists is to protect the page then put the section that's updated daily into an unprotected template, but this may be confusing for newer editors that don't know what a template is. The other solution that currently exists (that I know of) is to have admins and content moderators update the page daily until the edit war has calmed down, but that would be inconvenient for them and would leave the page outdated for longer since there are less admins and content moderators than total contributors.
It would be simpler to allow admins and content moderators to protect certain sections of a page, so they can protect the section with edit warring and allow contributors to update the other section that requires daily edits.
