Yeah 
To be honest, at least this whole affair was handled better than Spa-gate. There was a level of transparency involved and the stewards eventually got the decision half-right. But to be honest, the level of improvement between Spa and now needed to be much bigger. The weekend as a whole was handled well by stewards, it just all went wrong at the Trulli/Hamilton incident. I can see some major areas that need to be addressed, the first of these being total transparency, rather than the partial transparency that we have now.
Quicker decisions and more appropriate penalties are the next area. As for the FIA itself, the regulations need to be addressed. Loopholes need to be closed and the regulations need to be expanded to cover more possible potential infractions, as well as making them more understandable for every party involved.
Nice post, Denthùl! On topic, I'd just say that McLaren lied, and that's sad. About the stewards and the FIA, as you are saying, all it's needed is transparency.
Leaving things as they are now, the main focus is taken off the races and penalties and endless discussions are instead a more important topic. People start talking about conspiracies against McLaren, in favor of someone else or whatever. At least, it's nice that they at least revoked Trulli's penalty, he's one of the few straightforward and honest guys in this racing business

All I know is that, either way, the sport itself suffers from these afer-race events.
I hope the FIA are able to learn from the past and get the decision-making and the rules straightened out

I'd love to see 'em race twice in tracks like Spa. Second time there could be in reverse for all I care. Bring in Watkins Glen, Kyalami, Imola, keep Silverstone... and reduce those start-stop boring tracks! Asking too much, yeah.
