@klihub I think many of these are actually done. Should we close this issue and create new issues for the open tasks that we think are still worth implementing (if any)?

Hmm, I think only the TA/memtier merge is really done. We have a PoC/draft of dynamic policy switch+reflect-based config handling (a few months old already so probably a bit outdated wrt. more recent other unrelated commit/merged PRs). But we can close these and reopen individual items for those that we think still should be done and intend to do...
