The filter had no capability to remove existing tags until I added that as a safety net. If you control your metadata sources well enough, that's mostly a nicety, not that essential. If not, you probably have bigger problems. It really depends what you use them to do. If a tag turned on assertion signing or something like that, do I care really? Probably not.
