Thanks, paul. I have to say, i feel the key thing i did was in choosing
to adapt/reuse existing stuff - i think that more than anything helped to
assure it landing (once i got around to actually doing it!) Thanks are
really due to simon michael for doing the initial implementation.

There's actually another cost - recataloging the whole page just for a
subscription change - that makes this seem to be an abuse of the catalog.
I think i have a bit more hacking to do - i'm inclined to stem this abuse
early, before use is widespread. If wiki pages used subscription
instances as delegates, instead of as mixins, then just the delegate could
be recataloged on subscription change, much reducing the catalog churn.
I'm not sure this will significantly reduce the time to subscribe, but it
should much reduce the contribution to catalog growth.
