Pinnumbers are "numbers" in the first place. Former versions of netlisters/PCB
got confused by non-digital pinnumbers.

With this approach you have to have a SOT23 footprint with 1,2,3 pinout,
A,K,NC pinout, A1,A2,K pinout, B,C,E pinout etc. Sooner or later, your library
will contain duplicated data. What if you discover that you want to modify the
shape of the SOT23.fp footprint? You have to modify all of them. Yuk.

I think a footprint must have only *one* pinout, that is a standard pinout of
the package. Have an intermediate layer (scripts, database, pinmaps, etc.)
that do the heavy lifting for you.
