I'm sorry to hear that you too have hit this bug. It has got a lot of discussion on LP: #1724895. Normally I'd want to mark one as the duplicate of the other, but that bug has covered a lot of ground including cloud-init, so it's not super clear.
Perhaps we can use this to track the netplan-specific documentation issue and the parser error checking, and just focus on the weirdness with cloud-init in the other bug.
I will work on a docs fix - I think that's an important first step. I think parser error checking will be complicated because NetworkManager will set MTUs without a macaddress match (LP: #1769550), but I'll explore it as I have time.
