Using the neutral for the ground has never really been legal with two very specific exceptions, ranges and dryers. That went away over a decade ago.
Pools and spas are even more specific about this and if you are not abusing the exception about "existing" feeders you are required to use an insulated EGC in conduit in addition to the neutral.
Personally I would not accept a feeder installed in preparation for a spa as "existing" no matter when it was inspected.

I wasn't using any neutral for a ground. The SER has 2 hots a neutral and an uninsulated ground.
And the hot tub was completely piped with all THHN.
The missing neutral bar was an oversight on my part obviously.
As far you not accepting the subpanel wiring based on it's future use.
How would you know it was for a Hot tub? if the Sub Panel permit was pulled and closed prior to the application for a hot tub permit.
