I think it had two purposes:
  - It was an experiment, to help developing the WIDE_SOFT memory model.
    For example, if a gcc bug or GC bug was hampering WIDE_SOFT, to
    see whether it occurred also with the (less demanding) WIDE_AUXI.
  - It has immediate (= not heap-allocated) single-floats, so it could
    be useful for numerical programs that use single-floats on 32-bit
    platforms.
    But such numerical programs more often use double-floats, and
    nowadays 64-bit platforms are the norm.

Yes you can discard it.
