I agree with you completely on both counts.

Oh, man. Chosen family. One of my favorite things of ever, and I really, really, really like the way that plays out in the Gateverse with Sam&Jack&Daniel&Teal'c and Sam&Daniel&Vala&Mitchell (with Hammond and Landry in the mix as well) and John&Rodney&Teyla&Ford and John&Rodney&Teyla&Ronon and John&Rodney&Elizabeth and Rodney&Carson. I could satisfy myself with reading iterations of that trope and never need romance. LOL
