Expectedly so.

And since you seem to be surprised: There are a few people that
have just given up on commenting each and every mailing list topic,
so silence does not imply affirmation.

The main problem here is, again, that more or less independent
issues are mangled into one:

1. The intent to not use certain functionality in Qt *internally*
anymore.

2. The attempt to enforce those ideas on users.

They are not completely independent, but a 'Q_FOREACH' ban in Qt
proper does not have to imply its removal for users. If it is
not useful in your view, you can mention it in the docs. Breaking
formerly compilable code for no good reason is not a good base
for a 'contract'.

[Same for other 'helpful' deprecation activities or enforced
development restrictions]
