Looks good to me.
Previously, I unfortunately forgot that we have a addons/project/kateproject.example file, where we try to document a bit the changes.
Please add the ctags documentation there, as well. And then you are good to go.
Update kateproject.example with a basic documentation and a simple project example based on the example found at http://ctags.sourceforge.net/EXTENDING.html
