Sure, but my point was that once the new reindexdb is released (or if you're so desperate, using a nightly build or compiling your own), it can be used against any previous major version. There is probably a large fraction of users who don't perform a postgres upgrade when they upgrade their OS, so that's IMHO also something to consider.
