But that's not how memory works...you can't put your memory on hold like you're suggesting. There's a reason FSRS follows a personalized memory curve.

You can't, but I wager a student excited to doing a review but with a suboptimal method, will do better than a student who dreads the review with the optimal method.

Current algorithms/UI feel like punishment for over-learning, as if it was a suspicious thing that carried great responsibility to open a book and read a page without fully committing to forever maintaining reviews on everything you happened to come across. There should be no punishment and only reward.

Please don't make assumptions about my goals. I was clear about my requirements and asking for recommendations.

I haven't made any assumptions about your goals. I simply reminded you that memories kind of have "expiry dates", so that review dates are necessary. The backlog you mentioned is the memories you're about to forget if not "refreshed" in time. If you just want to practice whenever you feel like it, there are tons of apps that use a simple Leitner box, but you may soon find that it becomes a burden to review your cards if you add an important amount of them. Anki already has ways to do what you want, while still working according to your memory patterns, such as using filtered decks and lowering desired retention.
