Because we currently build Ceph with support with Python2, then the binaries end up "choosing" the Python2 interpreter and so the tests are all Python2 The other issue is that we found to be borderline impossible to toggle Python2/Python3 builds to allow some builds to be Python3 so that we can actually run some tests. I do expect breakage though, so the sooner we get to switch the better.
