One of the primary reason why we thought of going with this approach is
for out of the box "distribution" enablement. We thought, if the core crypto
algorithm sits in some git-hub code or public hosted tarball then the
PMD will never be added to standard distributions and which is a setback
for armv8 server ecosystem.

Having said that and as Zbigniew mentioned, We are open for revisiting
the crypto core algorithm and PMD split if there are community concerns
about export compliance. Let us know.
