I'd leave that to the maintainers' discretion, I can point this to the release as well if that's preferred. For me, this is not that critical, since it requires a specific scenario with multiple unreachable / misconfigured stores. I think so far we've seen only one report of the issue. |

Changes
As was reported in #4743, it is possible that if stores provided to querier are not available (e.g. the store is down, the address is incorrect etc.), trying to call the
/storesendpoint can result in panic. This is due to the fact that the status of the endpoint is missing information on component type. The suggested way to resolve this is to ignore such stores.Resolves #4743.
Verification
Added tests to verify
/storesbehaves as expected.
