Would

https://tools.ietf.org/html/draft-bormann-lwig-7228bis-06#table-1

have helped you?

This has a number of experimental classes above 2; both in the M Group (microcontrollers) and the J Group (general purpose computers — pun only accessible to people who know how Jeeps got their name).

Note that Sections 3.1..3.3 have more experimental categories; not sure these are useful for what you are trying to do.
