And I should also wait on the discussion itself, just noticed it. Thank you!
BTW, I know about a comment from Maps team and they told it is ok to turn on in every wiki that ask for it. If we decide to turn Mapframe in all wikis, why not, but wikis who want to have it in advance should have it (when possible, which is the case right now),. I don't think that enabling should be a problem, if unrequested enabling will be approved, why not.
