Therefore, you cannot conduct differences training on a single-seat aircraft -
My starting assumption also. However, nobody's yet done other than express opinions - mostly agreeing with my original assumption, Whopity thinking that I may be wrong. I'd like if anybody has a reference to see a document reference one way or the other.
You may be surprised to find that for a microlight class rating, there is no requirement for an instructor to sign off tailwheel differences
Actually I think that most microlight pilots knew that. I'm not sure it's ever caused a problem either - although interpretations that 3-axis.v.flexwing differences, and group-A.v.3-axis are sometimes not required have certainly caused accidents.
