> [BB] I should add that PLPMTUD and clamping the max packet size complement each other. 

Except that PLPMTUD works over authenticated or encrypted transport headers and clamping does not.

Clamping could be useful if the information were in an IP header that could be ignored by routers that don’t care (e.g, by not slowing them down, as IP options do).
