If you remember how e.g. Debian introduced first a pure amd64 (x86_64) arch
then backpedalled to retrofit 32bit libraries in there by adding multiarch,
then you can see how this difference in convention can be useful: if you
see one architecture as multi-ISA from the beginning you have the multiarch
as a direct outcome, not need for retrofitting anything.
