Wouldn't "delete all local overrides" (or "all local overrides added since 2018-09-27") be a reasonable step to include in migration after the "new translatewiki" is turned back on?
"Delete all local overrides" would be horrible, you'd lose all local wiki customizations. See https://en.wikipedia.org/w/index.php?title=Special%3AAllMessages&prefix=... for enwiki's customizations for example (although English might not be included in the purge), or https://de.wikipedia.org/w/index.php?title=Spezial:MediaWiki-Systemnachricht... for dewiki's.
"Added since 2018-09-27" would only be marginally better. Old overrides wouldn't be lost, but you'd still wipe out new overrides that are intended to actually be overrides rather than workarounds for this issue.
