Actually the work started long before THAT, even.  I think it dates to
1993 if memory serves.  Again, in my mind this is a matter of whether or
not the IETF wants change control, and I suspect that matters more to
the operators than to anyone at Cisco.  I am given to understand that
occasionally some operators get touchy about something not being a standard.

But speaking plainly, this isn't a science experiment.  It isn't
something anyone is floating as a suggestion.  It's what's being done in
the network today, and it is supported across multiple implementations. 
It is a defacto standard.  Unless there's very good reason not to do
so[*], let's just call it what it is.  And again, I would reiterate:
let's also make clear what it's not.  A good applicability statement
should help with that.

[*] A very good reason would be if it doesn't meet the requirements for
specifications that the IETF generally laid out.
