Create "inward" n-gon when beveling edge

it's not really an idea, more of a question, and if it's something Blender can't do at the moment, then a proposal. i want to bevel that selected edge (left-side image) and preserve the faces marked in green. i don't understand why Blender chooses to "destroy" the faces i have with that ugly n-gon (right-side picture), when it could just create a new a n-gon like the image below. is there a reason for this? could we have possibly an option in the bevel options window to choose where the new n-gon is created?
