This is silly to me - not because using multiple tags is better or worse, but because # TODO is something I see as primarily personal shorthand, and I think it's counterproductive to prescribe tags for people to organize their own code with. If my brain likes "TODO: fix edge case" and your brain likes "FIXME: edge case," that's okay. I guess this is relevant if you're using TODOs in the main branch, but I see that as rare. There are very few times I've had someone else pick up a TODO I've written, or vice versa. In my current team, if we're passing a To-Do/bugfix/enhancement to someone, that becomes a ticket and/or a Slack conversation.
