The role of Anki cards that force you to remember where a formula came from and why is usually played by the deeper material that builds on the earlier material. The trick is to reinforce understanding of the earlier material every time you use it, instead of relying on a reference or trusting the textbook. There certainly is a bit of an art to learning from textbooks on one reading.

On the other hand, adding a spaced repetition deck for the new material to your schedule permanently could keep the material from fading from memory in the long run, something that's hard to manage otherwise if you don't use the material regularly.

Sounds more like magic to me. I've seen research quoted recently that indicated people retain only about 2% of a book after a month of reading it through once.

Edit: Further elaboration, prompted by the downvote:

How do you reinforce understanding of earlier material without referring back to it?

And if you do refer back to it, can it still be called one reading?

Plus, If you periodically expose yourself to the same information multiple times, it's not much different from using a SRS, though one could claim it's less efficient, especially in the long run.

The sentence I quoted seemed to be making a claim for eidetic memory, hence my skepticism.
