This is very poor reason to kill it for everyone, 'I recall I may have
found platform where it maybe didn't work'.

Yet, it's super common go have L3Termination - L2Aggregation - Customer.

And sell various MTU options to customers, even use the L2Aggregation
as core between two L3Termination. All of these require per
logical-interface L3 MTU, while L2 MTU is usually set to max.

others too.
