My impression is that they have looked at the problem and think it's evil
and bad. Or perhaps more accurately, impractical and undesirable.

Based on my slight understanding, I think that doing TOE would require
vast changes in the way the kernel passes data and status, and given that
2.6 is a butterfly clawing its way out of the cocoon, there's no way a
major change is going to be made until 2.7.

I'm not suggesting that people will like the idea better then, but at
least the concept of major change might not be rejected, no matter what
the change might be.
