I did use Time Machine, but thankfully wised up and left for restic instead. Using Time Machine is worse advice than case insensitive filesystem if you ask me. Inscrutable logs and silent failures.

I’m sure there are those who found problems, but fact remains that in ten years I never have. What I have found is a lot of warnings against it by people who don’t use it themselves, like the person in the second link.

I recommend it, and the more people use it, the more people can help fix bugs they encounter (if any?) like in that last link you posted.

PS the Time Machine error in your third link is apparently about a CI source to a CS target. I hope it’s fair to say: don’t do that?
