I understand the idea but it'd be a very audience-dividng idea. As others have said, plenty of people type using rshift, myself included. "I never use rshift lol who uses rshift? therefore rshift is functionally pointless for everyone" is the same as saying "I hit spacebar with my index finger lol who uses thumb? therefore spacebar should just be on r3 somehow and here's a true ergnomic SKL (spacebar keyless) layout.". Of course if you just wanna make a keyboard for you, go for it! Just know you are actually alienating quite the userbase.
