It doesn’t return the Microformats JSON, it converts it to its jf2 format first.
It might be worth opening an issue on jf2 to see if they want to keep an explicit name
property. Their “author” syntax says it “consists of a name” and more, but that’s not marked as a MUST. For a jf2feed on the other hand name
is a SHOULD.
The real question is, do you see any reasons for postponing this change because of your use of a mf2 parser as a service? I think not?
