Maybe so, but the onus is on the person wanting to do the
deletion to provide a good reason. If COMPAT_ULTRIX is just a thin
shim on top of COMPAT_43 as somebody else has said, then is it
really causing a problem? As for lack of maintenance, it isn't a
moving target, so it only needs maintenance to keep up with related
changes to other parts of the kernel.
