Change Details

``` Follow-up PR for #18533 -- another small step towards getting rid of the confusing "command" terminology. Also see PR #18610 which tackled the functional tests. ``` Backport of core PR18937. Depends on D8460. The change to `process_messages.cpp` is not ported as this PR is deliberately ported out of order. The process_messages fuzzer was added in D8376 and reverted because it caused a TSAN failure; this diff is a dependency for the fix.
