Yes. One of the first "features" that I shut off.

...which still poses problems that should not be ignored. I forked a
subset of the main discussion in hopes of better idea organization.
Other protocols should indeed be considered.
It's a question of protocol-specific proxying when [at least for now]
DNS returns protocol-agnostic answers.
As a side note, I wonder how many users would notice a typo-intercepted
HTTPS side and associated invalid/bogus certificate. I'm afraid the
number would be rather low.

Agreed re the short term. However, SRV records have other uses -- why
should MXes get all the special treatment? -- so I'm trying to put
another tally in the "[potential] reasons to use SRV" column. Perhaps
if the ball began rolling...
