About the last sentences, do you mean all ucp wikis will have achievements and/or semantic mediawiki automatically enabled, all ucp wikis will be allowed to request achievements and/or semantic mediawiki to be enabled on their wikis, or wikis that have achievements and/or semantic mediawiki will keep those extensions after migration?
