Description

# Summary

Several community members have started using this feature via experiment variables `CACHE_GC_PERIOD` and `CACHE_GC_AFTER_NOT_HIT_DURATION`. They want to know when this feature will be mature.

Let's use this issue to collect feedback on this feature and improve when necessary before we move them to controller flags instead of environment variables. This is part of https://github.com/argoproj/argo-workflows/issues/8608.

If you are using this feature, please upvote and provide any feedback.
