It's perfectly fine to use it. It's just that the extra option
--git-export=WC is needed when you want to export your working copy 1:1
to the export dir (instead of only exporting comitted changes - which is
the default).

As you noticed having export-dir within your working copy confuses
dpkg-source which then finds your changes and wonders why they are
missing from the upstream tarball:

There's little gbp can do about this. You can tell dpkg-source to ignore
your export dir (see it's -I and -i options) but I'd rather move it
outside of your git repo.

You don't need --gi-export=WC after you committed the changelog. It's
only there to tell gbp buildpackage what exactly to export.
