No one is ignoring history. I don't feel like you're even listening. Whatever is intentional or unintentional, that someone notices will get talked about whether in review or opinion piece. And most often when it comes to Mario, it's an opinion piece to discuss the history and its issues not any one particular game. Talking of just Mario Oddysey, it's no more complex than Sunshine or Galaxy. Peach still gets kidnapped and Bowser wanting to marry her, the only difference is the ending where she essentially rejects both of them and goes on her own adventure. Also 3D World? She's playable, but now a bunch of female fairies are captured. Notice a theme and how the damsel in distress thing has not at all been addressed? things changed but everything is still the same and not even remotely more complex in your goals, etc.
Just because it got a few adjustments does not mean it has grown up, or matured, or a lot of things. To grow up with the audience, that people often demand is not being rated E for everyone. The entire point of growing up with an audience and its history of use from people and companies is to often reboot the IP to be for older audiences. Youkai Watch is doing just that, aiming for older audiences, the audience that grew up watching and playing it because their IP isn't reaching many kids as they once did.
I do agree with wanting a bit more changes to Mario on some subjects like I mentioned. But adjustments that people want from Mario, like I mentioned, is not one to age the series up with the audiences, it's to get with the times.
