Clustered databases do not support ephemeral columns, but ovsdb-server checks for them after the conversion result is read from the storage. It's much easier to recover if this constraint is checked before writing to the storage instead. It's not a big problem, because the check is always performed by the native ovsdb clients before sending a conversion request. But the server, in general, should not trust clients to do the right thing. Check in the update_schema() remains, because we shouldn't blindly trust the storage.
