I don't think the birthright claim of Munich on the bundesliga this season would really work that way as the league is becoming more competitive than usual with the current rise of teams like Leverkusen, Dortmund and Stuttgart, I don't think Munich will have it easy dominating and topping the league as usual and becoming the winners, I hope Leverkusen and Stuttgart is consistent enough to break this trend this season.
Well im not sure nor would i conclude that Bayern Munich would lose their dominance this season maybe cause of where they're currently on the standings,however i think the Bundesliga is becoming tougher currently and some clubs are now beginning to stand up to Bayern Munich not only Dortmun, if you noticed Bayern Munich almost lost their dominance to Dortmund last season luck was really on their side cause it was on the last day they managed to win and steal the title from Dortmund.
However this season the like of Leipzig, Stuttgart and most importanty Leverkusen are now standing up to Bayern, Leverkusen took everyone by suprise and are currently the league leaders, they've been dominating the league for a while before the international break and im pretty they'll their next match against Wolfsburg even though they're away from home.
I would not draw any conclusions even if temporary before the winter break of the Bundesliga. I have seen very often that after the early stage of the season it looked like some teams could stand up to Bayern, but the difference was that Bayern could increase their win rate while the other teams almost certainly were about to face a decline and have a loss or draw here and there. If there are a few teams with almost 100% win rate before the winter break, I am ready to think that there could be a chance for one of them this year. But I doubt it will happen if Bayern doesn't get unlucky with injuries. Kane is probably getting better over time once he is fully used to his new team.
