No, it isn't. The report clearly states:

"
While rebuilding the python related packages against the Python 3.15rc1
version we found that apache-arrow builds correctly [...]"-

There is no MUST for building against all pythons.
Building against multiple versions MIGHT be worthwhile (except when it'd be insane to do
that given cicurmstances/how python is used), but that is not "serious".
