Why would I want to obfuscate my code like that by purposely making 
people look in multiple places to figure out what it's doing? I don't 
see how this is any improvement.

If it can be implemented in an eclass, why would we want to do it as an 
EAPI in a package manager? Eclasses can be easily changed, you only need 
to write them once, and you don't have to deal with updating & approving 
a spec and new implementation for a bug in the previous implementation 
(which you have to retain indefinitely).
