cus-edit.el seems like the better choice for me.  When icons were added,
the functions to customize icons went in there.  The only difference
here is that the new functionality doesn't write to the custom-file,
rather to some .dir-locals.el.

Apart from a function that writes to the .dir-locals-2.el file, all
functions that manipulate the .dir-locals file are from files-x.el.  The
mentioned function is nowhere near smart as modify-dir-local-variable,
but I had to code it since I didn't find that to be supported in
files-x.el.  Maybe modify-dir-local-variable and the like could be
taught to handle .dir-locals-2.el too.
