Subject: [netmod] standards vs. research

Hi,

I have some concerns that the NETMOD WG thinks YANG is an
open sandbox that we can use to provide some really great
new features.  Documents headed for the standards track
should actually be more concerned with maximum interoperability,
rather than maximum new (unproven) features.

IMO, we should standardize proven concepts and technology,
even if this isn't always the bleeding edge in features.
The IRTF is available for that, not the IETF.

I know from RMON APM-MIB (and other) experience, that SMIv2 has
a 'complexity ceiling'.  If you try to create a MIB module
too complicated, it will never be implemented by anybody. Ever.
But it took us 10 years or so to reach the upper bound of
SMIv2 data modeling capabilities.  We started out with
much simpler MIB modules and gained interoperability experience
that way.

YANG 1.0 is already getting near the complexity ceiling,
and the 80/20 rule should be used to reign it in.

Andy
