This reminds me some people who open Jira tickets for every tiny things, then have fixes for these tickets.
A bug fix without an associated ticket is missing context: who spotted the bug? When? What were the steps to reproduce?
Even a ticket with no content is valuable - it gives me somewhere I can post additional comments and screenshots later, or link to other related tickets.
What’s not supposed to happen is have those analysed to be used as some dumb proxy for productivity/output.
