Clients can still choose to roll their own way of showing "is fetching", like how ClaimListDiscover displays a whole bunch of placeholder tiles. This just serves as a default.
The idea of using claim_search to indirectly batch-resolve didn't work out well. There's something wrong with the claim_search pagination where some results are duplicated in multiple pages, while some are missing. It's also returning less results that than the given number of claim ids, so sometimes the infinite scroll breaks.
