One reason to announce my intent was to basically "encourage" people to try HEAD and see how it works for them. If we lack sufficient people with access and/or knowledge about Windows, or if they don't bother to try things out until they get a tagged and rolled tarball (or whatever), then that is the issue that needs to be discussed and resolved.
Another reason was to also encourage people to practice some restraint against willy-nilly changes, so that the delta between the last beta and what we hope to go GA with isn't so large as to warrant YAB (Yet Another Beta)... Of course, bugs should be squashed, but YAR (Yet Another Refactor) should be carefully considered.
