Yeah, that's entirely possible.

How do you mean ... something that works for Fedora 13, 14, 15, 16
etc... ? We have that now, I just didn't include any details about how
the pages are updated when a new release comes along. Adam and I have
talked about an SOP to cover this, but we don't have any thing final
yet.
Having something that works for *all* releases of Fedora isn't a goal
for me right now. We have a process that works for all Fedora releases,
I don't think the pages themselves need to work for all releases.
They'd get far too cluttered with exceptions.

There are certainly some parallels there, but I'm intentionally ignoring
this for now. Not that I don't think both groups can't be served by
this, just that it's outside the scope of what I want to accomplish
right now. Right now, I'm looking to provide a way for secondary
architectures to extend/leverage the release criteria. I'm not looking
for a way to for SIGs to extend/leverage the criteria at this time. I
could see taking this up in the future.

I don't follow ... can you rephrase?

It's certainly in the back of my mind, and something we'll be looking to
see how well the architecture approach holds up.

I wouldn't say it has to, I intentionally didn't include that as a goal.
Personally, I'd like to focus on one of those targets at a time, and at
the moment the secondary architecture challenge is more pressing for me.
