32-bit code for most platforms is smaller *and* uses less memory
(pointers at least being half the size). There is often a speed
penalty too.
Right, and fewer instructions (for example, 5 instructions for a load
literal) but that doesn't mean there should be a codified rule - it
should be possible to have sensible enough packages that there is no
need for the installer or RPM to be too heavily hacked.
