If we are decided on adding a default path, please make it consistent with 
the other XDG stuff in ASDF...

I'm not XDG guru, but here's a link to the standard...

http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

It looks like default paths would belong under $XDG_DATA_HOME and 
$XDG_DATA_DIRS.

Looking at the current ASDF manual, it appears that there is already some 
support for this concept?

The source registry will be configured from a default configuration. This 
configuration may allow for implementation-specific systems to be found, 
for systems to be found the current directory (at the time that the 
configuration is initialized) as well as :directory entries for 
$XDG_DATA_DIRS/common-lisp/systems/ and :tree entries for 
$XDG_DATA_DIRS/common-lisp/source/. For instance, SBCL will include 
directories for its contribs when it can find them; it will look for them 
where SBCL was installed, or at the location specified by the SBCL_HOME 
environment variable
