Comment 11 for bug 316247

Andy is definitely right to reject this for 1.5. In fact, I see compelling reasons to to reject this even altogether:

- When a user accepts several tags, which item will be used? It will now choose an arbitrary one. I think this can only work if there's also some kind of popup to choose between a set of applicable updates, as in another RFE.
- It is not backward compatible. Note that (older) Sparkle versions without this feature don't know how to deal with appcasts using this feature (and they do get them!). And you cannot have the app updated before it checks ;-) I really think this should be a showstopper, as I see no easy fix.
- I don't see much of a simplification here. It just replaces one potentially confusing part (using different feedURLs) with another (using a confusing "tag", which doesn't have an obvious meaning). Beware of feature bloat, as it leads to confusion!

These issues (and perhaps more) should be carefully considered before applying this.
