Update from Manishearth: Now that migration to Math.SE seems to be reasonably high, I'm bumping this to see if we can get the migration path now.

One for the SE team: can we get an official migration path for moving questions from physics.SE to math.SE? A non-negligible fraction of the off-topic questions we get here are purely mathematical in nature and mbq or I wind up moving them to the math site.

Current stats (26 June, 2013):

In the past 90 days, 25 questions have been migrated from Phy.SE to Math.SE, with a 4% rejection rate (that's 1 rejected migration)

Could we have this now?
