If I didn't think we ever could change things, I wouldn't support 
documents like these.

The idea is to go to the ISP community and say "Please treat LE as BE in 
your core/peering links, and only act on it on the customer access shaper 
(optional). Please don't bleach it."

000001 has never been in use before, so the hope is that people will allow 
this to happen. CS1 has had different meanings over time so it's harder to 
handle.

The problem with CAKE/FQ and background traffic is that it can't tell if 
there is congestion or not, and things like LEDBAT can't backoff and try 
to avoid causing congestion. So your previous email about allowing some 
congestion to take place on LE would be good as then protocols that try to 
avoid causing congestion would have a way to do so.
