So you guys get to fly IMC "on your own discretion" with the support of all these fancy virtual view glass cockpit 3D rendered scenes, doing Cat-99 approaches with whatever MDA you pick, as long as you stay out of CAS.
Sounds like paradise for responsible people !
It is BUT I do not think it is quite the 'free for all' that you are suggesting:
1) IMC doesn't necessarily mean cannot see out.
2) If IMC then must be IFR. Which means not lower than 1,000' above highest obstacle within 5nm (of Track) of aircraft unless Taking Off or Landing in accordance with normal aviation practice. In IMC it is normal aviation practice to only land following published Instrument Approaches (and hence complying with their minima).
