The reports are convincing for me that it would be bad to revive the
old behaviour.

Most of the GNU maintainers at FOSDEM didn't know about the -C option
though.  Maybe it would help to publicise "-C" in the output so people
are more aware of it. e.g. 

    $ ./configure
     configure: not caching test results (use -C to enable)
     checking for a BSD-compatible install... /usr/bin/install -c

The message could be suppressed if config.status does not exist, so
it's only shown if someone is configuring more than once.
