After reading all archives of this month, I came to certain point but
now your words have confused me.

This is what Jonathan Shapiro said:

 It is true that the Coyotos *system* considers encapsulation of data
to be a fundamental requirement. If you cannot tell where data can go,
you cannot determine the scope and consequences of errors. For this
reason, the Coyotos *system* constructs confined subsystems as a

However, the Coyotos *kernel* does not embed this assumption. It is
perfectly possible to build other *systems* on top of the Coyotos
*kernel*. Given that l4-hurd is trying to be something very different
from Coyotos, it was never really my expectation that l4-hurd would
end up using much of the Coyotos *system*. The Coyotos kernel remains
a fairly high-performance alternative, I am not aware of any l4-hurd
goal that it fails to support, and I am not aware of any l4-hurd
anti-goal that it imposes.

So if Coyotos was abandoned for the reasons you suggest, then it was
abandoned for the wrong reasons.

Now I wonder why Viengoos was created as an alternative if Coyotos was fine.
