Most of us have appreciation in artistic approach of figure skating; that's why many long-time figure fans are nostalgic of the old 6.0 system. I believe transitions are there for that exact reason, making jumps more than just "boings". Without any kind of transition, competitive figure skating would be dance-pause-JUMP-pause-resume to dance, which has always been my horror; even with the new system, not many single skaters master their art like ice dancers do.
Jumps are one of many technical components that make up a program, just score more since it's riskier, harder and give visually instantaneous impacts than other ones. The old system may have allowed expressive programs, but (while some good programs had transitions) not all jumps were PART OF THE DANCE. Not that it's a whole lot better these days, but at least the rule encourages them to keep it in mind: jumps are part of the dance. Swirls(spins), snaps, glide(spiral), fluidity/cohesiveness(transition/flow), stretch/flexibility(!), jumps (!!!) etc. are all inclusive elements in dances such as ballet, jazz, hiphop, so on. Off-ice dances are judged on artistic impressions - and when scored, technical elements are scored in one way or another, as they altogether make up the art. Same with figures; techniques should be beautiful.
Ideally, we should separate single skaters into two leagues like pairs: single skaters and sigle ice dancers. However, there's only so many leagues the ISU can accommodate, not to mention insufficient number of profitable fans to promote quality skater candidates to fill the 2 extra pools. Or, we could have singles do one technical program and one artistic program where jumps are optional and treated as part of step sequence/transition/etc., but that's just my fantasy. (And I'm getting too excited with this fantasy, that I'm huffing.)
