Not sure what you mean by "addrequired bit."

If I understand correctly, Evan wants me to create an infrastructure
to allow pluggable coalescers.

I'd rather not do that right now as I've got a ton of other things
on my plate.  It turns out that I'll be writing another colaescer
sometime in the future so this functionality will be needed but
I'd rather keep this particular patch as small as possible (it's
already big) and do the pluggable coalescer infrastructure separately.

If I've got to write this other infrastructure now, it'll probably be
a few weeks at least before I'd have anything, and possibly longer.
I think it's best to get coalescing separated from liveness analysis
ASAP so Evan and others can make tweaks to both without disrupting
future patches.

Ok?
