Since writing that (quite some time ago, IIRC) I have joined IBM and
am now working with the people who did the JFS port. They
substantially confirm your viewpoint, with the added information that
the "old" JFS, now called JFS 1, is being phased out under AIX, and
the "new" AIX JFS, JFS 2, is based on the same code base as the OS/2
port. With that background, IBM's approach makes a lot more sense.
It's a pity that this issue wasn't clarified earlier.

I'm going to be doing a lot of work on JFS in the next few months. I
don't think I'll port it to FreeBSD, but I'll be available for
questions, and I'll have a better understanding.

You're aware that the original word of this phrase, "hon(n)i", means
"ashamed"?
