Multiple pyclass directories
We don't currently handle multiple pyclass directories properly. That is, if you have multiple repositories installed (e.g. a user repo) only one of those repositories (probably the openmw one) can provide the pyclass module, as the python importer will only search the first module in the importer load order.
Possible Solution: Create a virtual pyclass module somehow that loads each pyclass module encountered in the order of repository priority. Names will then be available from all repositories, and for those that conflict, the name from the highest priority repository will take precedence, since it would be loaded last and overwrite the old values.
