Clarify Stage 0 proposals requirements
Process documents seems to be invalid in regard of champion required. See tc39/proposals#71 for details.
Repeating my comment from https://github.com/tc39/proposals/issues/71#issuecomment-326613945:
The committee has been very clear that non-members can not bring any proposal without a member sponsoring it. Note, however, that's not necessarily the same as a champion.
In other words, stage 0 does not require a champion, but it still requires a TC39 member's cooperation.
Please let me know if you are looking for a champion for a proposal. There are many in the committee who are interested in helping out community members here.
@littledan I will be looking for champion after completing spec text for new Set methods.
Regardless, process document is misleading here.
