Agreed. However, by the time 3.9 comes out, there'll have been all
those years of changes. "The version after 3.9" would be a good time
to remove stuff that's been deprecated since 3.3 or 3.6 or whatever;
technically, that's breaking backward compat (hence 4.0 rather than
3.10), but in effect, it's no more breakage than a minor release would
give you (since you should have stopped using deprecated APIs several
versions ago). So there's still value in going to 4.0 around about ten
versions after 3.0; but it doesn't necessarily have to happen exactly
then.
