Well, this is a good point.

Hmm, not necessarily. For example, I would have liked to use the current
CVS version of gnatsweb on gcc.gnu.org, first to do some testing by
myself, and then also in production use. This I could do easily, but
having the entire GNATS installation updated, would be quite more
involved.

(I hope the upgrade path from GNAT 3.x to 4.x will be simple and well
documented, so that one can easily migrated his databases? Then it'll
be less of a problem for most regular sites.)
