I assume you meant "has passed".
Correct assumption.
As Ron posted, there is a standing (albeit, removed from publication) reply from John Lynch that says otherwise. It might still be legal as John's opinions aren't legally binding but I'd get a revised opinion from FAA Regional or Chief Counsel before taking that risk if I were you..
Good advice... if something went wrong on the flight portion of such a BFR, there might be more regulatory trouble than usual, because of the controversy
But I'll wager there have been such BFRs performed and signed off, uncontested, without notifying those parties, including John Lynch.
I'd be rather surprised if the majority of CFIs who've never been in a taildragger before could make a successful landing on their first attempt in a docile taildragger like a SuperCub let alone something a bit touchier.
I was rather surprised when I managed to land a Champ reasonably well on my first try (after 200+ hrs flying only trikes), but then again I'm not an instructor.
Assuming friendly winds, it's really not all that different, as long as you remember to use the rudder. The airspeed relative to Vs, the sight picture, and A of A in a 3-pointer is essentialy the same as with a mains-first landing in any high-wing nosewheel-equipped plane.
I did better on that first tailwheel landing than my first time landing a PA-32, which, in terms of the FARs regarding gear configuration, is the same thing as the Cessna 172s and 150s I've done most of my landings in (fixed; nosewheel).
But it sure is different to fly and land, between the gear/wing geometry and the weight.
The Champ, on final and when landing, felt more like an underpowered 150... not that strange to me.
FWIW, I'd be equally surprised if a CFI with only trike time would do a whole lot better landing any trike which is new to him or her, despite it being legally "the same".
In such a case, a small measure of common sense would go a long way ("can I handle this strange new type if this leagl-PIC pilot turns out to not be so proficient?"), just as it would in the tailwheel scenario.
