Of course -

An assertion is a statement that the application does not require some MPI standard feature or semantic guarantee. It is not a directive to the MPI implementation. The implementation is free to provide that feature or guarantee even if the application says it is not needed.

The story is a bit different for a helper library because the library is logically a more or less opaque part of the application. If the caller of MPI_INIT_ASSERTED says the application does not require something and then uses a library that does require that feature or guarantee - the library must raise an error or adjust its behavior to live within the assertion.
