I understand that it is obviously good practice to include a standard, and will hardly hurt anything, but why do you think it is uncommon in the modern literature? If it was so critical, don't you think reviewers and editors would be asking authors to include it?
do you have a convenient organosoluble fluoride source around you feel comfortable adding? hexafluorobenzene does sound like a good, common one. Many labs have tosyl fluoride (63 ppm or so) or just fluorobenzene (-112 ppm), which probably work just as well if they don't interfere in the relevant part of the spectrum.
