Even I usually just reach out to manufacturers, but if you do run into something that needs to be updated, you can always ask them, and if that doesn't work, you can always ask in the forum.
@Lugia, I think the biggest issue is with too many tags on a module, not so much with too little. A typical example of that is the Expander tag, which also comes with a bunch of other tags with the Expander does not do on its own, so, why would I want that to come up in a search where I am looking for that functionality? I don't, and yet I usually have to go in and edit tags out.
Oh well.
