I'll take most of what you said as being sarcastic, but your point is taken.
If tuned with a quality network analyzer, or with a return loss bridge and
high return loss terminations and pads, you will have pass performance
properly tuned. The only question is whether or not your transmitter likes
a real 50 ohm load. If so, great, you're done. If not, fix it.
With the cavities tuned to resonance, cable lengths are no longer an issue.
Needing to use "magic" cable lengths should be a red flag that you've got a
Z mismatch somewhere.

Even the demigods that hail from Waco, Marlboro, and Angola aren't
infallible, especially after the evil Brownshirt Brigade percussively
retunes their products while en route to you. All Hail Maxwell! All Hail
Maxwell!
