That might have been a factor but not a requirement. The reason back
then
was it simplified the timing and construction of the chip.

Use four bit wide cache parts then. Or if it's EPROM do three bytes wide
and
select the odd(right 12 bits) or even half(left 12bits). There are other
schemes
to reuse loose bits!
