I didn't mean to misrepresent you, but to me, that's an IETF-level
"implementation detail", rather than an IRTF-level issue. To be
maximally useful, it should be something which affects the
users'/applications' behaviour to avoid peak times.
The key is that the quantity you are both sharing out (however you do
it) is *congestion* rather than rate or volume.

OK, but "we" have the choice of letting loose algorithms which will
increase pressure to deploy it where it isn't already enabled, don't
