angle/time =?= frequency:
sure, based on SI base units, you're correct, but it's not for nothing
that '(plan) angle' and 'solid angle' are referred to as the 2 SI
supplementary units: "These are non-dimensional units that are sometimes
included in the dimensional expression of a unit for clarity purposes."
Hence, the magnificent 7 + 2 (optional) angle types would be nice solution
I guess
