I wasn't arguing one way or another what is better here, I was just
pointing out the difference given its important to this
change-right-before-release and that proton-j doesn't have an updated
SASL API/Impl to go along with it.

If it wasnt clear above, I only meant it might be pain to implement
and use isAuthenticated right now *given the older SASL API/Impl* that
currently still exists in proton-j and presumably isnt going away
before the next release.

My comment above was coming from an impression that the change here
wouldn't be close to fully aligning them, meaning further change and
probable breakage would be required down the line. If thats the case I
would tend towards leaving the existing default behaviour until such
time a viable attempt at converging them is actually being made, in
which case such change and breakage would be better warranted and
rewarded.

I'll admit I have writetn some Java specific tests in actual Java on
occasion....sometimes because I burned a lot of time first trying to
write it in python and found the test shim stuff entirely masked the
problem so I actually couldn't, and others just because it was a known
handful of minutes as a direct pure unit test versus indeterminate
time working out how the to do it far less directly via the python
tests that I simply justify at the time.
