I do not agree for footprints, because - at least if I understand the
proposal correctly - it will lead to many many different footprints of
the same housing, i.e. an SOT23-EBC, an SOT23-SGD (for FETs), an
SOT23-CBE, an SOT23-A1-C-A2, an SOT23-A1-C1A2-C2 etc. pp. with all the
same dimensional data but different pad names.

I came to kicad from Eagle some years ago and I still believe
distinguishing between symbol-package-device to be the best solution
for this problem.

In my experience, the terminals of a capacitor are not called cathode
and anode.

YMMV,
