I tried this, in the thread starting at
and continued on
(cross-posted to the autoconf list).

My arguments were not strong enough, so I applied the patch of the [[ ]]
proponents. The result was that a little more than one year later, a
quoting bug appeared in gettext.m4:

The lesson I learned from it is to prefer changequote. But I doubt that
1 bug that I introduced will be enough to convince people. More people
need to fall into the same pitfall and complain about it, until the
arguments for changequote can convince a majority.

I think this section in the autoconf manual was written because Akim wanted
to make deep changes to the way autoconf macros are processed, and wanted to
warn people ahead of time. It's a different motivation than the worry
"what leads to less bugs in the long run".
