Category problems again
We do plan to delete the templates in favour of the module someday, right?
If not (unless we plan to delete the module), that's bad; two massive, complex records will never stay synced without a very smart bot watching them.
But if so, I suggest that when that day comes, we have someone (I volunteer) go through the module and the templates by hand, deleting templates one by one after checking that they are correctly in the module, and reviewing any codes that the module contains that templates don't. If possible, we speed up the process by having a bot make a list of all codes which are in the module but not the Template: namespace, or vice versa, or which are in both places but with unidentical contents, and by having the bot delete all the templates are not on the list (i.e., which are in the module), before the human reviewers come in.
