Are you aware of a TCP implementation in an OS that shipped within the

I am not, but I'd still be vaguely interested in an actual study :-)

The last time I tangled with v4 pMTUd it actually was a decade or more ago. At that time wholesale ICMP blocking caused 
all kinds of problems for clients with a sub-ethernet MTU in their path. If the world has moved on, that seems good :-)
