Yes, I think that's a very sensible strategy.  The uptake of the
format in the wild has been very rapid, so from now on we'll want to
be really, really careful with how we evolve it.

While that is a constraint, fortunately we're seeing pretty
non-trivial things done with the format in its current form, and the
design of our metadata machinery (already in place, even if it's
unexposed yet UI-wise) makes me reasonably confident that we'll be
able to keep this for a while.

Ah, the burden of users ;)
