Well, one of the tradeoffs here is that Informational track allows
something to grow into a solid standard without also having to pass
the same level of up-front scrutiny and commitment that a Standards
track item does. I rather doubt that either the DBAPI *or* WSGI
would've passed that scrutiny in early days, and the "free to ignore"
part means that there's a lot less pushback on the minor points than
generally occurs with Standards track PEPs.
So, I'd hate for us to lose out on the *next* DBAPI or WSGI due to an
implied pressure of needing to get it right in the first
place. (Indeed, I think we need *more* Informational PEPs -- in
retrospect there was probably some point at which I should have done
some relating to setuptools and eggs and such.)
Overall, though, I supposed there's no problem with promoting Final
Informational PEPs to Standards, *unless* it creates an expectation
that Informational PEPs will become Standards and they thus end up
being debated in the same way anyway. (Of course, if it generally
takes five or six years before an Informational PEP usually gets
promoted, this is unlikely to be a major worry.)
