When an account is deleted in Thunderbird, we ask the user whether to delete the local account data together with the account itself.

It struck me now that there could be a use case for the user to actually uncheck "delete account" and only check "delete messages". In that case we could just wipe the data folder (local directory) and at next restart (or msg fetch) TB will recreate it and download messages anew. This could be useful for debugging (no need to recreate accounts) and e.g. for IMAP accounts accumulating junk (e.g. folders that grow and can't be purged/compacted).
