I’m curious, if the team implemented the suggestion of being able to cram level 12 items, would that work for you?
I’m trying to find a compromise, since if the team were to expand beyond level 12, I’d imagine that would mean adding even more sentences, which takes up time from features they could add elsewhere. (And given other threads on here, people are also itching for other things to be addressed as well.) Since cram is already a thing, I’d think it’d be easier to focus on touching that up, rather than spending another year or so adding dozens of more sentences for additional reviews. (And even more years beyond that, as I imagine people would want unique sentences, since ghosts already get criticized for being memorizable.)
For me, I’d rather they focus on patching up any bugs, finalizing N1, and such, rather than only ever doing more sentences, which I could easily get from just reading native material. 
Would adding those sentences from the native material you consume also not satisfy the suggestion? It gets the added bonus of being from material you already enjoy, and since you know it’s grammatically correct, it’d make for nice extra study questions. (And help you work on the badge, if you care about badges.)
Genuine questions. Just trying to find faster/easier solutions to what you want.
