David, I agree with you, though I'm not sure about the end user
experience:

We had the same situation with ECN and window scaling, and my proposal
is the same as how we handled those situations involving broken
middleware boxes.

Yes, that is true. IMHO there's a slight difference with FRTO trouble
compared to ECN/window scaling issues:

ECN trouble -> No access at all
Broken window scaling -> Large transfers don't work
MTU issues -> No access at all / large transfers don't work

FRTO problems -> Hard to spot as they only happen when packet loss occurs.
Though I guess Ilpo knows best if there's an "easy" way to detect this or not.
