Another problem with ice dance judging that I think was evident at the Olympics was the ridiculous emphasis on footwork and steps over the creativity and innovation of lifts. Lifts are the most exciting aspects of ice dance for me, usually, and the best teams at that are definitely D/L, Den/Stav, and Del/Scho. I doubt I will find more teams in the past, present, or future who can come up with better lifts than they create on the ice. However, the top three on the podium were all teams with, in comparison, very boring and unoriginal lifts. I think with N/K, B/A, and G/G, the judges emphasized difficulty (although not speed, because the Russians and Ukrainians were SO slow) in footwork sequences and twizzles over lifts, which I found to be a real shame to the sport.
I wouldn't take issue with most of your other points, but I think you're letting your personal love of lifts overpower a perspective of what ice dance has been historically and will or should be in the future.
(Do you by any chance enjoy pairs more than dance in general?)
The one thing that dance has always been about as opposed to freestyle is steps to music. Even in freestyle, people have often referred to "dance steps" when the focus has been on expression of rhythm.
Historically, dance lifts were meant to be brief and to express the character of the music rather than to be athletic feats as in pairs. With the loosening of lift restrictions in dance and especially under the new system, the difficulty of the lifts has become more important and the timing rules measured in seconds rather than measures of music has decreased the relationship between the lifts and the music. Many would contend that that is not a good thing.
Some of the rules and trends for step sequences have also decreased the relationship between the steps and the music as well. Again, purists would argue that that trend loses one of the defining characteristics of ice dance.
Look back at the OSPs from the 70s and 80s, and you'll see that they were all about difficult steps, turns, and edges to the music, with ice speed a plus but not the only criterion, and quickness only important when that year's musical rhythm was quick. No lifts, no dance spins. You did see those, especially the former, in the free dances.
Personally, I think it's great that the difficulty of what the blades do on the ice (in the steps -- obviously one of the partner's blades are not on the ice at all during lifts) is explicitly one of the most important criteria in judging dance.
I just wish there were a way to explicitly reward and thus encourage creativity and specificity to the music in all technical elements (steps, lifts, and twizzles and spins also) and transitions. Yeah, those things get covered in the component marks, but there are enough other criteria to the components that they're not necessary to win, and unfortunately some of the current requirements for the technical elements are structured so that it's more rewardeing to structure the elements to gain points rather than to express the music.
