As to motivation, I suppose (since I wasn't involved yet) that it was roughly:

    let's bite the bullet and fix unicode with a backward-incompatible release

which led to:

    well, we're already going to break backward compatibility so we might
    as well get any breakage we're planning over with now so folks only
    have to fix their code for this release

and then to:

    oh, and while we're at it let's clean up a bunch of cruft that's built up
    over the years

At least that's my impression. :)
