Not at all. I said I have some ideas, on how I'd like things to be, (I'm a bit of a amature writer) but that's head canon (purely as a hobby) which has no more meaning to canon than fan fiction, I acknowledge that freely.

Hey you're free to disagree. I don't agree with everything disney has done but it's a Fact.

Another reason is thats not his original armor, in the new canon book that came out about ahsoka he had to ditch his old stuff for reasons. Don't want to get into spoilers too much. So it's possible the notches could be from someone else.

Actually the movies and the 2008 clone wars series, and rebels along with the new books have been established as part of the new canon. Agree or not, the higher ups at disney already decided this.
