What
plugin update, plugin details, plugin enable, plugin marketplace update and their siblings no longer carry their own inline description strings; all of them read from the shared table that also hides early-access entries, so help text and the subcommand listing cannot drift apart.
Evidence
"Update marketplace(s) from their source - updates all if no name specified"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
