The answer doesn't really matter. Storing atoms that do not show up in 
any of the modules, is a mis-use of atoms, just like any other use of 
such atoms.

list_to_atom/1 is for the shell to be able to create the atoms you type 
(and for dets to do the above).
Almost any other use of list_to_atom/1 is a misuse.

If you feel the urge to use list_to_atom/1, just say no.
If you obey, you don't need the answer to the above question.
