When it is locally done, I find it hard to see what isn't too like. That is, if I open an email and it asks if I want to make a reminder or add it to my calendar, that is cool.

When I see that several emails I have not opened are already on my calendar, I am less happy about it.

I don’t really see what’s different, honestly. They’re moving it from one system they control to another, big deal. Plus who says I even saw the original e-mail?

If they have given a side channel to impact my calendar, that will cause issues.

Sure, for many folks this will be fine. But it seems an unnecessary denial of service attack vector that needs more engineering to protect than makes sense.

I would guess in the many years they've had this they've had to iron out some issues, but allowing you to receive e-mail at all is a denial of service attack vector.

True. But it is only a denial of your email service. Allowing it to leak over to other services is not good.

You could think of them as different facets of the same service, like Exchange.

That can still be done locally, no? You don't have to open an email for the phone to retrieve its contents.

I meant locally to be in my sight.

That said, I'd also assume that full emails are not sent to my device until I open them, unless I setup something.
