Fan surveys were in favour; majority of drivers were in favour - but of course it's a formality that it would be rejected...
There are two parties not seemingly in favour: journalists and, from what the journalists tell us, teams. From which I can only surmise the following:
1. It's in the interests of the majority of teams to keep the status quo. I'm not entirely sure why, but I would suggest that it may be because pre 2009 there was an even greater 'glass ceiling' in F1, with lower level teams less able to score points than since - particularly when Pirelli tyre lottery afforded them random chances for reasonable positions. A system which would allow better tyres removes the random element the tyres introduced, so these teams would prefer to steer in the direction of mixed up 2012.
2. Journalists are working on a combination of two falsehoods: the information supplied by the teams (presumably coloured by the above interests); the notion that more overtaking equals better racing.
The latter is simply not the case, as I and others have demonstrated throughout this thread. An easy overtake adds what to the show? Very little, in fact I'd argue that they become devalued as a result and the audience somewhat desensitised - you actually water down what should be a 'high spot'. We had an issue in the 2008 and before era where it was certainly too hard to overtake - and the high spots too few and far between - but when the ill conceived 2009 changes did not work, f1 went radical in ensuring overtakes happened and in so doing devalued the product.
On the team side, there's also a notion that mixed up orders are something fans want - again I think this is a fallacy. Did fans enjoy pure head to head battles between two teams such as Schumacher/Hakkinnen era or 2007/2008 era more or less than 2012 where there were 8 different winners at the start of the season? I would argue most would say the former.
This is because, I would suggest, a head to head rivalry between two titans head and shoulders above the rest is actually a more easily digestible and more intriguing story than pure unpredictability. One team dominating is no fun, but it's the nature of sport that it sometimes happens - you get into unsporting territory when you try to manufacture a 'good show every time' (and, again, it becomes devalued).
