There are few issues that were raised earlier on this topic. We should mark them as resolved (and close the issue), or mark them as non-blocking for stability for cardinality limits.

How do you want to mark them as non-blocking? @cijothomas

I feel this issue needs a resolution before this can become stable.

TC can leave a comment on the issues saying "it is not a blocker for stabilizing cardinality limits feature spec".
(I don't think it worth creating github labels like blocking-cardinality-stable, allowed-cardinality-stable, nice-to-have-cardinality-stable etc, so a simple comment can help.)
