For the time being, using

  \DeclareExpandableDocumentCommand{\foob}{}{FooB}

solves my issues, except for

  * this warning from xparse documentation

        "This facility should only be used when absolutely
        necessary; if you do not understand when this might
        be, do not use these functions!"

    because it applies to me,

  * \DeclareExpandableDocumentCommand doesn't provides all the
    air bags \NewDocumentCommand, \RenewDocumentCommand etc.
    have.
