Rediscovering properly the power of macOS Mail app

Yeah the title would make you think that it's going to be a long post but no.
Beyond accessibility, beyond even the OS, there is one very subtle thing I think people should realize. There is a whole culture and ecosystem around an app, brand, OS or a combination of any those elements.
In our little echo chambers with Windows, NVDA and Chrome, when we are using everything or most thing from Google, including Gmail, we tend to forget that not every other email service has a web interface which is the primary and is as good as that of gmail with an insane load of feature set and accessibility to go with. I was used to think that everyone using an email client is just dum because everything is web. And with how good NVDA is at handling complex modern web app, my transition to macOS, especially with Ventura being my first version ever experienced, was just horrible.
A brutal TLDR to end this because I ran out of token... I have very recently transitioned from Google Workspace Starter to iCloud Plus with custom domain emails, both of which I was already paying for, the domain and iCloud Plus. The transition and especially the import/export of emails all within the mail client was the most seamless and Apple ish thing I've seen in a long, long time.
PS: I heard the drawer disclosure sound only now when I was properly exploring the insane amount of logs we get in the mail connection doctor, when we hide/show details. Any other time where we have this or this is near death?
