It's not a "bizarre choice", it's how AIX works. If people want to use
cfarm119 for testing on AIX then having an unconventional installation will
mislead them into thinking things just work on AIX. But then users with a
conventional AIX installation will hit the problems instead of the devs
testing on AIX.
