What you want seems a bit 'backwards'. You want is to bypass info (notifications), to get to a screen were you are require to use finger input, so what's the point?
The point is that if you do not care about notifications the extra swipe is totally unnecessary, and an annoyance considering how many times the phone needs to be unlocked per day.
Imagine if you hade to do an extra swipe every time you wanted to use the keyboard despite already having placed the cursor in a text field? Wouldn't you find that annoying, despite expecting to perform finger input?
On top of this, your assumption is incorrect. I frequently wish to check something in the frontmost app without performing any type of input. Examples include booking details in an e-mail, the length of the latest phone call, information from a web page or a calculation result in a spreadsheet.
