I'm going to chip in here and say that making a negative X in an auction where partner has opened a minor and the opponents have overcalled the other minor should show 4+/3+ in the majors (either way). There're still 'death' hands, especially over a short C opening with a 4243 shape or similar - but there are fewer terrible hands. Having a heavier 1NT bid (where available) also lessens some of the pressure; and I'm not sure why you'd rush into declaring 1NT with 6 opposite 11 when the opps know what suit to lead at trick 1.
