Two things it could not do, both needed now that a tag ships to production.
Release notes: it never sent `releaseNotes`, so Play's "What's new" was whatever
the previous release said. It now takes --release-notes-file, and refuses text
over Play's 500-char-per-language cap with the actual count — that check has to
happen before the upload, because the API only rejects it at commit, by which
point the AAB is already on Play.
Promotion: --promote assigns a versionCode that is already on Play instead of
uploading, so what reaches production is the byte-identical artifact the testers
ran. Rebuilding would mint a fresh versionCode from possibly-newer sources and
ship something nobody tested. --promote-from asserts the code really is on that
track (a typo'd versionCode now fails before it touches production) and clears
that track in the SAME edit, so the build is never active on both at once.
--user-fraction comes along because --status inProgress is an API error without
it; it is validated as strictly between 0 and 1 rather than left to Google.
