Depending on hardware capabilities, this may be indeed intentional,
for example to keep the size of the SPL below a certain limit or to
allow for other, more critical features instead.

This may well be possible.  But then, this is usually stage two
already - the ROM bootloader did not check any SPL checksum
either...
