My local group has been using those exact rules for about 2 years now. The eldar player wasn't happy that his pathfinders couldn't hide from markerlights, and I didn't like the fact that my stealth suits apparently only turned on their cloaking fields on when targeted by plasma guns.
We recently took a step back to see what effect the changes had had on our games, and we're pleased to report that they've had nothing but a positive impact. D-weapons now have a hard-counter that doesn't rely on psykers, sneaky assault units don't have to hug cover to get a chance to shine, and invisible deathstars are few and far between.
It's also worth noting that for Stealth/Shrouded we count Ignores Cover weapons as ignoring the
BS penalty.
