Yep, that clip is what led to my thoughts about possible aero gains/advantages!
I think it's unarguable that the cars have made a leap forward in the last few years - and it's brilliant to see the current cars being taken as far as possible - but, with the current balance between works/private teams, I do think Chunder has a point with regards to spiralling costs.

Unknown. I didn't see anything further on the matter (at least in the public domain) and, as the GRC regulations aren't available to the public, it's impossible to say if the GRC introduced any measures to control ECU/software usage.
As you say, the ECU/software regulations in the World Championship should prevent that from ever becoming an issue.
