While it might not be the intention, certainly configuration test
is not the same as syntax check, and would never be. The idea
behind configuration test is to be able to check that nginx will
be able to start with the configuration in question, but without
actually starting it - to avoid interference with already running
nginx, if any.

Configuration testing may have side effects, this is expected.
Some of these side effects are documented at
http://nginx.org/en/docs/switches.html, though certainly there are
others.

If you think that the documentation is insufficient - consider
submitting a patch to improve it. If you think that certain side
effects should be avoided - feel free to submit a patch to avoid
them.

Not sure it's a good idea.
