Subpart is a better idea. Can be shared by several parts.
Somehow I also feel that a primitive should be an object,
one unbroken object and not separated objects.
How much space do you really save?

Well, that is actually an interesting discussion!
Quoting http://home16.inet.tele.dk/hassing/l3p.htm#lgeo
I found out that we (mis)use stud4.dat by scaling its height by 5 in bricks!
(and other factors in other parts).
LGEO uses lg_plate_cylinder and lg_brick_cylinder
and we should use two different studs in LDraw too.
Primitive primitives (grin) like cylinders and discs are OK to be scaled,
but studs should never be scaled - or they cannot be substituted correctly...
The stud4.dat's in 3001.DAT (Brick 2 x 4) look funny now,
because the rounded corner gets scaled by 5...
The same goes for stud3.dat.
