I have a carry-on hard case, which is certified for the cabin. As a matter of fact the airline I most often use sells it branded as carry-on luggage.
it can happen, though, that I have to check it at the gate if the plane is an Avro 100 (or something similar small) and full.
This is actually quite nice in Vienna, when my connecting flight is a Dash turboprop plane. I have to check it at the gate, put it on a cart at the plane entrance, but can pick it up immediately after leaving the plane with no wait times at the carousel.
Even though I see your point, I don't think it's practical.
