This is why IMHO pilots should be required to take an LST to revalidate their SEP just as with the multi.
IMHO an FAA style BFR is better - which is signed off by the instructor as a logbook endorsement, which certifies that they have completed the BFR successfully. That way, should anything crop up in the near future, the FI takes the rap from the FAA. It means examiners are not needed, competent pilots are not unduly hindered, and no hassle. If the date is passed, fine you can't fly until it is done. Forget any hours requirements too...
