mq Deprecation plan

$/!\$ This is a DRAFT for discussion, and does not represent any firm decisions on future behavior.

1. mq features we don't yet have a replacement for

Maintaining a "floating" patch that can be applied and unapplied at whim. Use case is patches like "add debug logging." People want a well-known name they can reference. This could probably be done with unshelve that doesn't delete the bundle.
export/import/graft between repository workflow isn't as simple as cp
Easy discovery of "local" commits/patches. hg qseries easier than hg log with a custom revset (revsets aren't approachable to newbies)
