YES!! YES!!! You are correct!
We did not have any Girl's programs around our area so my two girls played all the way up and through Bantams with the boys.
Then one of the local high schools offered a Co-op opportunity for some of the area girls to play on a all girl's team.
A girl comes down the wing and my girl angles her off into the board. Not a check, no banging into the glass. The other girl gets separated from the puck and falls. You hear OMG from everyone in the stands like someone was robbed. It is not an open ice full body check??
Referee hears this and blows the whistle, penalty.
It is a learning curve for my daughters. They look at me and shrug their shoulders and head off to the penalty box. They do not say anything to the Refs., they no better.
Their Coach understands where they played and the boys game. They have not played on a girl's club team. They said "Dad, if this is what it is like playing with other girls they rather play again with the boys". But, they understand they are in High school now.
From what I have seen there is plenty of contact (angling, pinning, etc) that doesn't get called. I don't think big hits would add anything to the girls' game, and would likely result in a lot of concussions. That is not sexist, just science: girls suffer concussions at a much higher rate than boys in sports like soccer. Girls hockey is still a very dynamic game with lots of change of control, unlike for example girls' lacrosse.
They're called b00bs, Ed
