Its more an issue of the external links
Just a thought on this, but assuming that the move were community-approved then would it be possible to do a sort of "hard-redirect" where http://en.wikipedia.org/wiki/Main_Page (or http://en.wikipedia.org/w/index.php?Main_Page if you like) would automatically shunt any incoming traffic to the new page? Isn't there something in Apache, a 500-level code maybe that a server gives to clients to indicate a permanent redirect so that the incoming link can be updated? If this was the case, and since everyone agrees that moving Main_Page is not an immediate concern but rather a long-term issue (or not an issue at all), then Main_Page could exist for the next six months or year as an un-editable "hard-redirect", to give the world's links time to be updated. Then after that, once the epic novel "Main Page" has been written and achieved verifiable notability, we can un-hard-link the Main_Page article and editing could begin.
Is any of this plausible?
