OK, I should modify 3rd party application that use autoload.el so they
use loaddefs-gen.el instead. But please let me confirm one point.

When some .el file is moved to lisp/obsolete, is function defined
in it unavaiable any more?

cl.el was also moved to lisp/obsolete before. But I use some 3rd party
applications/libraries that use it and they still works (or seem to
work) well.

Is is just by chance?
