The above sentence is troubling to me too.  Take the old adage "one 
man's victory is another man's defeat". In that - I mean -- who's to 
say that an ATOCA (layer 3-7) solution adversely affects a layer 2 
solution (existing or planned)?  This is nearly always in the eyes of 
the beholder.  The IETF, for the most part, deals only with layers 
3-7, and leaves lower layer solutions to other SDOs. The classic 
example is wrt IEEE.

Put another way - if you are a proponent of the WARN act, you like 
the 140 character limitation for any message.  Most of us in the IETF 
feel that's too limiting, and believe we can create something that is 
much more useful.  Now, anyone that MUST be in compliance with the 
WARN act needs to support at least the 140 character limitation. Does 
that mean there can be no other communication with a richer set of information?

Some might say that idea alone "adversely affect an access 
technology" because who implements both are taking on increased complexity.

Is that a reason to stop progress?

In the 50s the railroad industry tried to prevent the airline 
industry from becoming certified, at least in the US.  The rail 
industry say the airline industry as a threat.  Now, was that effort 
good for anyone?

If someone doesn't implement what the IETF specifies in ATOCA, then 
they don't implement it. We let the market decide -- of course where 
jurisdictions allow.

I am opposed to the suggested change to the charter.
