So my naive question of the day is:
Does anyone have any practical case for an IPv4 path MTU within[1308;1348[ ?

I'm starting to think we may need an MTU BoF or MTU wg. There arejust so many issues sourrounding packet sizes and fragmentation, andthey're dealt with in a rather fragmented way currently.
