And I see that 3551 obsolete 3550.

This is also a trivial change just as are the suggestions which are
outlined in the latest changes which have not yet made it into the rfc e.g.
the -new documents which bears the same rfc number but changes wording.

Anyway we have other problems to worry about  besides this.

All I know is that my application will not comply with this old way of
thinking and without having the source code one person won't even really be
able to tell why the calculation is giving anyway.

I have already shown in my own server implementation that existing software
works the same if not better using my values as recommended.

I will write a new draft regardless of what you do with this errata but I
suggest it is not rejected without proper reason.

...

Please also check out the errata related to rfc2326 and lets try to get
somewhere with that...

Sincerely,
Julius Friedman.
