Who is right or wrong is a matter of historical perspective.

The fact is this:

All current/modern DNS clients will support the resolution of a CNAME as part of a MX expansion process.

No. That should be '_Many_ current/modern...' or even '_Most_...', but to say 'All' is presumptive.

Well Pardon me!

To me, "Current and Modern" DNS client software takes into account the idiosyncrasies of the system, including this very common issue. So if a current/modern DNS client is ignorant of such issues, well, think what you wish - it will be viewed as "buggy" and if you deal customer service business, it will be your problem.
