Yes, the messaging involved with the "ext3" vs "ext4" bump has been
really unfortunate. If I had to do it all over again, I would have
created "ext3dev", and then when it was stable, I would done a:
git rm -rf fs/ext3 ; git mv fs/ext3dev fs/ext4
For example, it would have avoided the problem with SuSE product
managers refusing to support ext4 for multiple years, etc.
It also would have avoided the problem with people doing comparisons
of ext3 versus xfs, even in April 2014 (see a recent Hacker News
promoted blog article, where in someone kvetched that ext3 didn't
support fallocate). Sigh....

Yes, it's likely that for 1.43 we'll enable various features by
default. It's been quite deliberate that I haven't enabled by
default, because I wanted to make 100% sure they were completely
stable before enabling them by default. Some of them we may have been
able to enable by default earlier, but be that as it may, 1.43 is a
good time to make that change.
