So, with a situation like what Simon describes above what tends to fix the issue of the (generally) default TCP MSS of 1460 not fitting inside of this. Does path MTU discovery tend to fix this, or does change TCP MSS on a CPE (or BNG?) tend to fix it instead?
Two reasons for a content provider to force a small TCP MSS:
(1) Working around broken networks that filter ICMPv6 Packet Too Big messages (2) One less RTT than waiting on an ICMPv6 PTB
I don't condone any of the above reasons.
I realise there is this ideal world where we don't have to transit networks beyond our control, but why is (1) not condoned in your view?
