With the new system (without !!FUZZY!!), it's impossible to tell that a user has confirmed a fuzzied translation, because there's no edit to the translation and there's no log. This produces mysterious summaryless diffs to translation page when all goes well and nothing at all when something goes wrong or it's not page translation (with all sorts of problems for attribution and understandable histories), see bug 46716 comment 4. A log entry should be added.
This also causes https://gerrit.wikimedia.org/r/#/c/66574/1/AccountAudit.i18n.php where doing a full export of an extension finally removed the # fuzzy comment, even though the actual unfuzzy had possibly taken place a long time ago. Two expected behaviors based on this issue: I. Marking unfuzzy should make the message group qualify for export if it's a file based message group. II. Marking unfuzzy should be visible in the page history of the translation.
