That's basically the idea.  *If* there is a validation mechanism, and
*if* the module uses the validation mechanism to assert it is "Standard
LaTeX", then when you change the file, you must ensure that the module
does not validate as "Standard LaTeX".  This can be done by removing the
validation mechanism from the base or by causing the file in question to
not report itself as standard.
