The slight problem with that claim is that it's incorrect; the
constrained-deduced syntax wasn't added at the last minute.
The other problem is that while you're entitled to calling whatever
you like nonsense, there are significant technical
advantages to the approach we ended up choosing (Nota Bene: this "we"
excludes the author of the email I'm responding
to, as he wasn't a participant in any of it, so feel free to take his
reports on what happened and why with a modicum
of suspicion, as it's not based on first-hand experience), so there
are plausible reasons to think that it's far from nonsense.

I don't think the degree to which I personally participated in anything is of interest to anyone - my statement is based on the official minutes of the meeting where requiring auto was suggested and voted on.  Perhaps "last minute" is inaccurate, I withdraw that part.  And of course it being "nonsense" and "bad syntax" are both in my subjective opinion.  No, I don't have hard evidence that the majority feel the same way, it's just an impression.

The slight problem with this claim is that it has no evidence backing it.

Yes, well, we need consensus for all proposals, so this was hardly any
special exception.

Yes, both of those things are indeed possible. The proposal here isn't
seeking to overturn that decision, though.
