I'm kinda skeptical about that because if those allocations are occassional by nature, we don't care and if there can be a huge number of them, splitting them into a separate cache makes sense. I think it makes sense to pin down exactly which caches are memcg managed. That has the potential to simplify the involved code path and shave off a small bit of hot path overhead.
