That's a dangerous position to take. See "experimental" EAPIs for instance, sometimes temporarily supported by portage, but NOT for use in the tree. But I think you knew that and simply made some assumptions with the statement that not all readers may have. > This is the entire point of the EAPI, that we don't have to wait X > amount of time before using new features.

As I've seen it stated, an EAPI must be approved by council before ebuilds using it are allowed in-tree at all. Procedure there seems to be that final approval does not occur until all three PMs support it. (See EAPI-3, now preapproved, but conditional on feature implementation, with removal of some feature or other possible before final approval if not all PMs support it in a timely manner.) That's for in-tree. For arch-stable, the qualifier is no longer all three PMs, but only portage, as the default PM at this time. When a portage version supporting the approved EAPI is stable, ebuilds using it may be stabilized as well. But I agree that the point of EAPIs is to avoid delay, and that once an EAPI has final approval (as I said, itself conditional on working implementation in ~ versions of the PMs), there's no need to wait longer to put it in-tree as masked or unstable. And for stable, once a portage with the approved EAPI goes stable, so can packages using it. That's my understanding of council and QA policy, anyway. I'm open to correction just as I tried to correct the parent, if needed. -- Duncan - List replies preferred. No HTML msgs.
