Having dealt, some years ago, on a regular basis with some of the "core"* XFree86 members, I am confident that they feel thoroughly vindicated by the course of events.
Yes, that's right. Best not to think about it too hard. ;-)
* XFree86 disbanded its core team contemporaneously with the mass exodus to X.Org; my guess is that they twigged correctly that there was no point having a "core" development team when there was not going to be a "periphery".
