That's the thing you don't seem to understand though. What people in here are doing is going by the canon we have. We were already told by the games and Aonuma/Fujibayashi that BotW takes place at least 10000 years after any other zelda game. Then TotK takes place a handful of years after BotW. Whether as a historical fact or legend, all Zelda games take place in the past of these two games.
It would make no sense for Nintendo to now change their mind and say that these two games are no longer connected to each other, nor are they connected to the rest of the series.
All you've said is there should be no retcons, work with the canon you have. That's it. It's contradictory because the timeline you posted, would be retconning what was previously established.
You also make it seem like you only go by what's in game to prove any connectivity, yet here you are ignoring it for a timeline shared at a showcase, with no proper context to it.
