It does feel like going "backwards" in a sense. We have the three flags
mostly split, and we'd lose that distinction. On the other hand, if the
current split is imperfect, it may be leading people down a confusing
path (I _think_ this "trees must be set in order to see blobs" thing is
the only real gotcha, but there could be others).

There's some other discussion in this old thread:

(I didn't remember it, but my spider sense tingling caused me to dig in
the archive a bit).
