Well, if this is to be a "+gzip" suffix, it presumably represents a compressed form of the base media type, which might reasonably be expected to be a single object.  Certainly in the case of the motivating use-case (tlsrpt).  Though, admittedly, this not a proof that some media type might not in its gzip incarnation become multiple compressed streams. If there is a plausible use-case for such a thing, then the recommendation to ensure that only one stream be present would apply to various specific use-cases, such as "tlsrpt", but not generally.  Feel free to ignore or use these and the previous remarks as you see fit...  They are not blocking objections.
