The small MTU immediately removes it from contention for certain small/medium business last mile connections (sites that are too small for their own PTP link, but more valuable in $$$/mo than a residential user). This is because 1480 makes it impossible to do MPLS.
There are all kinds of things that could require an EoMPLS tunnel such as a centralized wifi captive portal system, or branch offices of the same small government entity in a county (ex: Libraries, schools, whatever). Radio systems functioning as layer 2 bridges need to support 1600 byte MTU. That's pretty much standard for all equipment these days. Even ubnt got their act together and fixed the MTU issue, I believe it used to be not larger than 1500 on the very earliest series of AirMax/N radios. Issue has been fixed for a few years now.
