Well, actually I would rather not add any new features between pre8 and
rc1 to not further delay 2.2. And generally I'm also not in favor of
adding new features during the rc phase as it's there to eliminate
remaining bugs and for refinement of existing features, not to add new
unknowns.

This I'd definitely delay as it probably affects a number of things.

Mostly a matter of finding the relevant spots, the actual work to
implement it would be trivial. Could be considered as bugfix.

Also requires little actual work, question is only if this should be
enabled for EAPI=0/1 as well, and how it relates to USE_EXPAND and ARCH.
If it should be done for existing EAPIs as well could be considered as
bugfix.

If someone implements it it can be included (do you want an EAPI bump
for that?)

Only if >99% of the stable and ~arch tree and all potential "system"
packages build with it (IOW: no)

Already implemented.

Unlikely for 2.2.

Should be trivial to implement off-hand (just converting the existing
defaults to wrappers)

Should also not be terribly difficult, though I'd rather wait until
after 2.2 final.

Unlikely for 2.2.

Well, I already said everything about those during the first discussion
round and the relevant council meeting.
