Adding my vote to enable locking the wiki. Would like to use the Wiki to store "work from home" information that shouldn't be changed.
EDIT - I just learned we should be able to control this via SharePoint. Find the "Teams Wiki Data" for that site, click "Manage Access" from the ellipsis menu, and set Members to "Can view."
EDIT 2 - That didn't work. Sorry.
