It might be useful to have a list of bugs (like the "depends on" and "blocks" lists) for bugs that have mutually exclusive potential resolutions. This would probably be used mostly with feature requests, but would probably also get used for UI issues.

Ooh, I like this. This would really come in handy now and again for patch triage... If a patch is written for this before 2.16 ships I'll bump it to 2.16. For now, most enhancements are going to 2.18

Enhancements which don't currently have patches on them which are targetted at 2.18 are being retargetted to 2.20 because we're about to freeze for 2.18. Consideration will be taken for moving items back to 2.18 on a case-by-case basis (but is unlikely for enhancements)

Bugzilla 2.20 feature set is now frozen as of 15 Sept 2004. Anything flagged enhancement that hasn't already landed is being pushed out. If this bug is otherwise ready to land, we'll handle it on a case-by-case basis, please set the blocking2.20 flag to '?' if you think it qualifies.
