This is off topic, for which I apologize, but your new avatar photo is absolutely stunning.
To redeem myself, I shall report that at DD's gym, too, it's "no giants, no L7," and the girls do not compete L6. Some of our L7s, however, compete giants that are still very much in progress. DD, who is headed into her second year of L8, spent much of the summer cleaning up her giants, and they are much better now than they were. I'd guess that some gyms might have moved her up but not had her compete giants at L7.
I'm very curious to see how the boys' side will work, as the coach will be moving boys up to L8 who don't have all of their group requirements covered on every event (DS is likely to be missing one on hi bar, though I am thinking now that he might make it on rings). We have one guy pointed toward L8 who's having a lot of trouble with giants right now. I sure hope he gets them cleaned up, because I don't think it's possible to do even the most minimal hi bar routine without giants, is it??
