There are, of course, physical limits. There's no doubt that if you relax constraints - which is what Sigma did with the classic ARTs - you can increase performance.
However, I do believe that - with modern design techniques - you can increase the performance and reduce dimensions at the same time.
There is probably also no magic in this if you compare a new design with the predecessor which may be 5-8 years old. Time doesn't stand still in lens design as well.
I reckon we are all curious about what Canon will come up with the new RF 70-200mm f/2.8.

I doubt that this one is any worse than the classics. However, it'll probably also more expensive again ;-)
Of course, there will always be examples where this will not apply.
