For the most part, yes.

It's actually not lacking there, though it's not obvious.
Similar to XFN, which uses the context of the page to understand the "from"
of the relationship, xFolk, also uses the context of the blog to understand
the "person" who is doing the tagging.
Thus since this information is already available in current usage, it is
actually *undesirable* to grow xfolk to represent person as well. In fact,
that violates the modularity principle.

Yes, and will stay open until someone can demonstrate significant use cases
for a stand-alone datetime elemental microformat. So far, all use cases
have been as *a part of* something else. Hence it's a design pattern rather
than a full fledged microformat. We should only create new microformats
when we can demonstrate that there is a clear need. Formats for formats
sake are outside the scope of microformats.
