" First migrate all users to the v2 variant, all of which are tests. However, to be able to properly migrate all tests off it, a v2 variant of the restricted reader is also needed. All restricted reader users are then migrated to the freshly introduced v2 variant and the v1 variant is removed. Users include: * replica::table::make_reader_v2() * streaming_virtual_table::as_mutation_source() * sstables::make_reader() * tests This allows us to get rid of a bunch of conversions on the query path, which was mostly v2 already. With a few tests we did kick the can down the road by wrapping the v2 reader in `downgrade_to_v1()`, but this series is long enough already.
