I would agree that XDG is over-engineered and under-specified.

However, ls finds dot files just fine (alias ls="ls -A" if it helps), and 
"normal users" usually install programs in "system directories", not their 
home directory.

Given the current CL ecosystem, things are constantly changing, 
implementations provide little fasl compatibility, CL installs are often 
per-user, etc.  Thus the current best default for sources is in $HOME.  I 
would argue that the use of $HOME is the real problem, and "hiding" things 
is the right solution for users (as opposed to developers who can be 
expected to memorize a slightly obscure path).

Two default paths is not better than one.

There is a reason MS Windows has "hide system files" enabled by default. 
Some things are too complicated for "casual users", and an obscure 
"~/common-lisp" is just asking for grandma to delete the folder she 
"doesn't want"...

In systems like OS-X-style "disk images" and Java-style jarfiles, the 
entire application is self-contained.  Thus it is quite appropriate for 
the full path to be user-visible, for deleting the file is uninstalling 
the app.

P.S.  In case I've gone off-kilter, I promise to get some sleep before any 
further replies.
