I'm open to supporting by appropriate design all kinds of upper layers
people want to experiment with. Review feedback for that is welcome.
However I don't intend to implement each of those myself, and hardcoding
them is not really an option so they must be in appropriate modules.

Do keep in mind that depending on vendor implementation we have between
26 and 2048 bytes MTU available, less based on regulatory requirements,
often below 256 bytes. The more space we take away for frame headers
just because they're somehow standardized will make it less useful.

Regards,
Andreas
