Would it be useful to allow work on it, maybe including a deferred
approval (ie, PEP is approved for implementation in version 3.3 [or
"when the moratorium is lifted"]), to proceed on a branch?  Branches
will be very cheap in hg.  I realize this may "bring work forward" for
you and other interested parties, on the other hand I think there is a
"strike while the iron's hot" aspect for implementators of the PEP.

In particular, having a working and approved feature on a branch would
allow those interested in the deferred PEP to merge into a (private)
fresh branch for compatibility testing of the work being done on the
mainline.
