One possible solution for the partial plus complete h-card issue is to include a link to the full h-card and not mark up the partial profile information on the home page as an h-card. The representative-hcard-parsing algorithm would then follow the link and use its full data. It doesn't seem ideal, but it'd work.
If you did this using the rel-me markup, the home page usually has many rel-me links and we don't yet have a way to denote the "canonical" one.
u-uid and/or a new rel-canonical property could be used for this.
