>  
> What exists already:
> * suppress() is in the smoke-test topology (SmokeTestClient#183,195, 
> untilWindowCloses)
> * that app is driven by streams_application_upgrade_test.py
> * LATEST_4_3 is already in smoke_test_versions
> What is missing:
> * No system test sets dsl.store.format. With it unset, the new code writes 
> byte-identical
>   V3 records, so the current test would pass on trunk too. Needs a 
> HEADERS-configured variant.
> * The harness is upgrade-only: to_version is hardcoded to DEV_VERSION and
>   restart_all_nodes_with() only moves nodes forward. The downgrade direction 
> has to be built.
