  • selectMyChannelClaims depends on byId, which currently is always invalidated per update, so it is not memoized.

  • Most of the use-cases just needs the ID or the length of the array anyways, so avoid generating a Claim array (in selectMyChannelClaims) unnecessarily -- the client need to reduce it back down to IDs again :/

  • The simpler boolean also removes the need to memoize the selector, which saves a bit of memory.
