That depends on your definition of the work "necessary".

If you mean do you have to have it to make anything grow then the answer is no but if your going for the ADA look or trying to maximize the ADA growing system then yes you need the power sand

The one thing you don't need is the bright sand since it's the same thing as pool filter sand just nicer looking but again that's depending on the look your going for.

There are many prior threads to this topic, you might check there, however, I've found no need for ADA PS.
It's mostly a source of NO3 at the initial stage.
It gets mixed up if you uproot with the aqua soil and are not careful, then looks tacky(while large pumice + blackish aqua soil).

I've long used ADA AS alone and have excellent results.
Some have claimed the PS helps prevent anaerobic conditions, this is not true either. Plant roots add their own O2, this is well known, studied and understood by anyone that's ever bothered to study wetland and aquatic plants. Same thing with heater cable arguments.

As far as adding a long term source of extra nutrients, osmocoat is pretty darn cheap. I don't bother, ADA As has the lion's share of the nutrients anyway and leaches a great deal in the first 1-2 months anyway.

As far as the ADA look, no, not ever remotely close to being required.
Aquascaping and a method are independent of each other. Always has been.
