If I send a Structured Discussions comment and my session became invalid in the meantime, e. g. because I logged out in another browser window or tab, then the edit will be made under my IP address, with no warning whatsoever that it would be permanently recorded in the page history. The Flow extension should use assert=user with its API calls to avoid this. (See T124451 for a similar issue in Wikibase/Wikidata.)
