I believe that this portion of LU (and most of the original codebase of
LU) was actually acquired by Sun as part of a technology transfer from
another vendor with a SystemV derived UNIX. A large ARC review for
the whole wad was held in 1999.
I believe that this other vendor made that choice. It appears that an
ARC member asked about the wisdom of using FMLI, but I was unable to
find the answer to this question, except for the following statement:

Sadly, that hasn't yet happened; my understanding is that the funding
for this project has never materialized.
The current position of at least some folks I have spoken to on the ARC
seems to be that our rules prevent us from removing lu(1m) until a
suitable replacement is designed. I'm not sure I agree with that
argument, but then again I'm not in charge :)
A great project would be a prototype of a LU GUI.
