On that I agree.  CLOCC does feel a bit "monolithic".

Nope.

MK:DEFSYSTEMs are ASDF-INSTALLABLE for one thing.  Doing (REQUIRE 
"some-mk-defsystem") on CMUCL works as expected, and above all, the 
setup of MK:DEFSYSTEM is now much easier.

Essentially you just need to tell MK:DEFSYSTEM where your packages are, 
without having to link in the .system file (provided that the package 
unpacks in a directory contaning a .system file with the same name).  
Moreover, now "component" systems work intuitively and can be made 
dependent on other components as well.  This considerably facilitates 
the construction of hierarchical systems (witness the struggle I just 
went through to make CLSQL build under Windows).

Of course.  I have no problems with that.  I just want people to know 
that MK:DEFSYSTEM is live and well. :)
