For one thing, I now have to be logged in on my mail on the device I am using, and that means if the device is unsafe, I am exposing far more of a risk that way.

It also forces me to look at my email inbox, which can be a pretty annoying thing if I am trying to relax and now see some email with bad news - requireing me to break the flow again.

Most important however: it is simply wrong and not needed. The flow has been settled.
