And surely, this specific issue did not come from users through a bug
report.

Not really.  I've come to *agree with you* that we should just ignore
those that don't find the transformation useful for real code: they
are vocal minority.

You can have all the sarcasm you want, but maybe instead of sarcasm, you should produce real data to contradict our bug reports, and the experiences of other compilers in the field (note that Seongbae Park tells me sun had the same level of complaint, i.e., one report, about their compiler doing this as well).

Basically, your argument boils down to "all supporting data is wrong,
the three people on the mailing list are right, and there are millions
more behind them that just couldn't make it and have never complained
in the past"

Don't buy it.
Put up or shut up for once.
