I think the problem with Drafts is that they are really not finds yet. They are another source of information that would need to be integrated to all the information that is already available for each combination of each user and each cache. I do not think it would be "hard to fix", but it would require a lot of work to implement this functionality in all the tools.
Using some mark for caches with drafts in map and possibility to exclude these in the tools would be nice addition and would make some things easier, especially for people with long backlog. For many people, it would be just a nice to have feature (icon), but the rest (who do not use drafts or are keeping up) would probably not even notice.
This makes the impact of this feature very low (affecting small portion of people) so I would rather see some other features and bugfixes that have impact on more people.
