I try to do both.

Maybe... I don't say that I read all the details, though.

Because the generated files changes should be reviewed, and by freezing
that there won't be new changes with new autotools.

The reason is
"change to sources files can have no effect on generated files and this
can be very confusing when unnoticed. "
So, yes I am all for having AM_MAINTAINER_MODE set, but it should be
used only to notice that something was modified such that the maintainer
understand what is happening and fix the timestamps and verify what

But by doing that you also generate a new output file.

Indeed in general it is better, but here it is not exactly the same
because the generated files have a double role.

Sure, but in the case of the autotools generated files those files
may have non-trivial consequences.

No problem, I am not sure that we disagree that much, we should look
at particular reviews to know for sure.
