Nice how you left out the work of one key developer in this whole thread.
The sort of developer who didn't make sure he was in the spotlight all the time and also didn't get paid for any such development.
He left a year and a half ago, after more than half a decade of high X dedication.
He worked on modesetting, a driver subsystem no-one before 2006 ever bothered to care about (especially not those people who are verbose about it now, as they were the opposite then), and his driver supported features that really were years ahead of his time there.
He was the first to provide actual EXA support in his code, beating others by a month or so.
He put the code XGI released in 2005 right there were it belonged.
Yet apparently, that person is to be ignored completely, now that people finally started to care about X.
I'm reasonably certain that this is exactly one of the reasons why such a valuable and highly clued developer throws in the towel.
Do some digging.
