It is a strong requirement, and it is indeed the default, and this
requirement is compatible with the CLHS 3.2.2.3. Yes it is
substantially different than ASDF. Note however that if this irks you
a lot you can disable the CFASL functionality.

You can also do that.

But if a function is used by macros, you'll save a lot by doing the
right thing, i.e. putting that function in an EVAL-WHEN.
