And some skaters will go beyond that to tell stories or paint pictures or engage the audience with their skating, and they will largely be rewarded and certainly not penalized for doing so.
Under any system and any rules, there will be some skaters who are not naturally extroverted and not naturally musical who might decide, correctly, that their energies are best spent perfecting difficult technical skills and who will win by doing so successfully, while more fan-friendly skaters with weaker technical skills (or weaker mental focus in competition) attract more fans but win fewer medals.
At worst, that might lead to skaters who temperamentally could choose to emphasize either technical skills or performance skills choosing to focus on technique under IJS whereas they would have put more focus on performance under 6.0.
But the really driven ones will try to excel in all relevant areas -- and if they succeed it's even more exciting to see a performance that's strong in all areas technically (not just jumps) and artistically.
And the skaters of artistic temperament who can't develop the skills to win under IJS would most often not have won under 6.0 either.
