I assume you're doing it this way to try to make Kodi more user friendly, but when the key stops working because TMDB invalidates it for whatever reason, you then have millions of users experiencing the frustration of having it not work. Then you go generate a new key, update the metadata xml and release the update. Then said millions of users hit your add-on repository to get the update which I assume you pay bandwidth for. Only to be repeated again when that key gets invalidated.

Yes, I use my own key.
