@embray - to just add a bit more about this: the problem is that there simply aren't conventional names for these units, because even `f_lambda`/`f_nu` are not actually *units*, but rather physical types (`f_lambda` is sometimes per angstrom, sometimes per nm, sometimes the energy unit is eV, sometimes it's erg).  Jansky is the only named unit with these units, and it has a radio-centric scale that makes it not useful for other fields, anyway.  So I think it's just there's *no* good option.  Anyway, as @pllim said, these aren't user-facing so it's not too big of a deal.
