Agreed, I use underhooks all the time, especially against taller opponents and I do throws from that position as well (this is under muay thai rules too). Getting the underhooks are a important skill that transitions well to wrestling.
Its not like Western MT seems to care about this change so i don't really either. I used underhooks for 4 or 5 of the clinches in my fight and scored two really big illegal takedowns so i'm a fan of them still :P.
Here's a good example of a "post-rule-change" fight at Lumpinee. The referee breaks the fighters up when one fighter (usually Saenchai, the shorter guy) grabs the other (Petboonchu) around the chest/waist, and whenever activity in the clinch otherwise slows down.
Saenchai vs. Petboonchu
This was s a great fight. Enjoy.
I've always though of reaching for underhooks as a pretty dangerous way to escape the plum, if someone already has it cinched up. It gives a pretty open window for a knee to the chin.
