There are many cases where accounts are created for known-non-spammers by other Wikipedians mentoring them, but our current implementation won't trigger the 'autoconfirmed' group on them any sooner.
As a result, perfectly legitimate folks are stuck with hardcoded restrictions until a certain number of days or edits; this is rather inconvenient when training people, doing user testing, or mentoring a new user in person.
Until we've cleaned up the autoconfirm system so we can make the temporary restrictions more intelligent and manipulable, let's go ahead and add a 'confirmed' group on enwiki and commonswiki with the same permissions which can be switched in manually.
Go ahead and dump the 'uploader' group on enwiki also, since that was meant for a subset of this use case.
(Note Jennifer and Frank will want some accounts set up this way for a Wikipedia Academy event in a couple weeks.)
