Yes, Solaris 2 was one of the early adopting systems. I would guess it was
as late as 1993. You have to remember that the End-2-End networking
theories only really won the argument late 80's early 90's, and before that
store and forward concepts like X.25 designed (and remained popular through
the mid-90's).

There aren't actually, because you can't be sure of your path, it is a
matter of dynamic tuning like your window sizes, round trip times and
transmission rates.
ATM gets round this by mandating a pathetically small fixed cell size (I
suppose you know how they arrived at it?) :)
Does anyone know anything more about ECN, and whether there's gonna be DoS
attacks if anyone takes notice of it, with faked packets with ECN bits set?
