Q303: What separates a homebuilt from an ultralight?

A: Ultralights and Experimentals may both be built by the owner, but
the ultralight may carry no passengers (except for
instruction).

Didn't the FAA sunset the exemption that allowed dual instruction in
ultralights as of Jan. 31? I thought that all dual training is now only
allowed in registered aircraft?

If so, you may want to drop or somehow revise the answer to that question.
