"It's the way of kitchen sink," I believe.  You need global design sense
beyond solving in-the-place issues.

Take a look at sparc or arm32 about processor encapsulations.
Primitives depending designs and parameters could be treated in a
similar way.  Wiredown handlers are of subject.  Taking locore
routines into parts should be considered carefully as it'd be easily
result in tangled codes.
