I actually don't think this is a good idea. The issue (sort of) came up with a merge request I posted previously, but honeycomb is, in my opinion, actually not a good tag anymore. There are currently 3 versions of Android which are referred to as "Honeycomb": 3.0, 3.1, and 3.2. There was also a similar request, but in the opposite direction.
The problem I see is that the 3 Honeycomb versions actually use 3 different API revisions. As an example, some USB APIs were added in API level 12 which were not available in 3.0, so tagging honeycomb on a question regarding USB interfacing could result in answers which are totally useless if you're targeting API level 11 (3.0 devices). I think it's actually important to at least keep the version specific tags around, though I also think they should be encouraged over the more vague honeycomb.
