I kind of understand this part about bringing non-avalon components into 
Avalon, and also I don't completely agree with this (without further 
thinking), my question was a bit about different thing. Your 
argumentation can justify redefenition of "Avalon Component" term to 
include all Objects. But why deprecate all existing Avalon Components 
(now you have to go and fix'em all and fix all your containers which 
expect Component - Cocoon's case) by deprecating Component interface? I 
mean, you can extend definition of component and include all this 
non-Avalon thingies out there (if you see that it's possible and adds 
value), but this by itself does not require deprecation of Component 
interface. Which means, there is something more to it...
