FrankR,
With the FAA not currently approving the reduced course, it could easily become an issue later on, however only for aircrew, that holds the FAA ticket or would aspire to get one. There's still a lot of aircrew only operating on validations of their EASA licenses, and always have done so, who probably wouldn't care, combined with perhaps thousands of hours on the G IV-X or G-V, too do a reduced TR.
