A previous comment asked if we should also have a deferSpec identifier here, and the thinking is yes, since that version of the protocol still isn’t guaranteed to end up as the final version.

We were thinking of using 20230621 as the identifier (as a reference to this doc)

[jerelmiller]

These tests weren't actually testing defer but a regular query that emitted multiple values. To be honest, I'm not sure how useful these tests are given this should theoretically never happen in a real application (at least for queries). That said, I just removed the @defer in the queries for now since it was misleading since it wasn't actually testing defer payloads.

I've moved @defer tests to their own subfolders. This test still exists in src/core/__tests__/client.watchQuery/defer20220824.test.tsx
