I don't have a strong opinion, but I observe that it's common for
complicated products with configuration file(s) to provide a specific
way to locate the configuration file(s) (such as the "-c" command line
option).  So it probably makes sense to have a dedicated switch just
to specify the configuration file(s), and, for that, it would be
better to name it accordingly, that is, something like --config-path
or --config-file is better than --data-path.

And, assuming we do that, regarding whether we want to keep
--data-path: again I don't have a strong opinion, but if currently
don't use it for other purposes and don't have an immediate concrete
plan to use it for something else, I'd apply YAGNI and just deprecate
it.

BTW, maybe on a related topic, I wonder why we have both --config-file
and --data-path (or if renamed --config-path).  Can't we unify them?
