You might as well, as long as it's always guaranteed to be encapsulated in the exact same format (DON'T GET ME STARTED on DLT_PFLOG!). If you submit it with a patch, that'd be even better. "Wireshark can read XXX" generally beats "Wireshark can read YYY so it can read XXX after you run it through XXX-to-YYY".
