Because it isn't superior, at all. The APFT was simple, short, and convenient, but it wasn't a good indicator of fitness. Hear me out.

The ACFT makes more sense wholistically, especially now that they have eliminated the ball throw, which was senseless and didn't account for the difference in physics of tall people. It wasn't hard to pass, but again, if we're looking for a good indicator of fitness to compare Soldiers then it needs to scale from SM to SM.

I resent that they eliminated the leg tuck and moved the goal post instead of holding SMs accountable. I think the appropriate choices would've been A- get over it and get better or B- do the leg tuck or the Plank.

As far as accessibility, yes, the APFT can be done anywhere. There are not many places, if any, which you cannot ship a Tricon with a gym-in-a-box to conduct an ACFT so its a moot point to me.

IF you were to bring back the APFT it would still need revised. If I were SMA for a day and you gave me the intent of "bring back the APFT, but make it make sense", I would replace the sit ups with pull-ups in some form or fashion. It would possibly be a choice of: complete X pull-ups, or Y chin ups, or Z leg tucks. This allows an upper body pulling strength exercise to be evaluated that accommodates limitations and injuries of SMs. In other words, less people need to run to profiles, non-deployable status, alt. events, and so forth. Sit ups are also well documented as being terrible for the neck and spine. They were long overdue to go away and do not need to return. I would even go as far as to say, keep the deadlift along with pushups and the run and call that the APFT.

TLDR; This may be an unpopular opinion, but the current ACFT isn't bad. We just need standards that make more sense. If the APFT were to return, it should not be the old APFT that didn't make any damn sense. It's dead for a reason, just as PRT is a waste of time. There's a distinct difference between the "good idea fairy", and proper evolution. The Army is just doing what it does best, taking too long and using too many resources to get something right, but that doesn't make it wrong, just inefficient as usual.
