I see three reasons why this argument may be flawed, but I think we are
confusing the meaning of subpart.
1) The Pxx number are all two digits, so 973p4.dat should never exist.
2) The same pattern on a part varient would be demand a suffix for the base
part number, so in your example would be named 973ap4.dat, not 973p4a.dat.
Indeed we do have this situation for the minifig head - we have a 3626bp01.dat,
but equally there should be a 3626ap01
In summary (N=numeric, A=alpha, X=alphanumeric, P=P, C=C, S=S)
Base parts ............ NNN.dat NNNN.dat NNNNN.dat
Variant parts ......... NNNA.dat NNNNA.dat NNNNNA.dat
Decorated base parts .. NNNPXX.dat NNNNPXX.dat NNNNNPXX.dat
Decorated variant parts NNNAPXX.dat NNNNAPXX.dat
Shortcut assemblies ... NNNCXX NNNNCXX NNNNNCXX
Mini-parts (*) ........ NNNSXX NNNNSXX NNNNNSXX
True subparts s\NNNPXXC.dat s\NNNNPXXC.dat

That's fine for users of more recent CAD tools, but would deny LDraw users
access to the decorated parts.

I still see no reason why we could not use 973pa1, 973pa2, .. 973pa9, 973paa,
.. 973paz. Subparts only need to be named to avoid conflict, so there is no
real reason why any subparts for 973paa.dat could not be named s\973paaa.dat
s\973paab.dat.
