Name Forms are a component of DIT Structure Rules. If you don't use
DIT Structure Rules, then you don't have name forms either.

A name form is only a primitive element of the full specification
required to constrain the form of the DIT to that
required by the administrative and naming authorities that determine
the naming policies of a given region of the DIT.
The remaining aspects of the specification of DIT structure are
discussed in 12.6.5.
RFC 4512 quotes
Name forms are primitive pieces of specification used in the
definition of DIT structure rules
So it explicitly specifics no other use apart from DIT structure rules.
However it does not say that "these rules do not apply without an
associated DIT structure rule" neither it says it does.
