I think a change like this will highlight the essence of modern F1. For each function it boils down to:
How well do I understand the contribution this function makes to winning?
How well can I implement that understanding in software?
The first has always been there in F1 but over the years the second has increasingly amplified it’s effect so that lots of small understandings can be knit together to make a big difference.
I think one team excels at both and I think this change will emphasise their understanding and ability to implement that understanding.
