Is the recent Appstream guideline for fonts [1] applicable for Gnome Software?
While reading it for preparing the metainfo.xml, I noticed these following lines:

<id/>: For fonts, the %{id}must be the name of the font or font bundle without whitespaces, and must be suffixed with.font.

Can ".font" be omitted because majority of metainfo.xml lacks that suffix?

<provides>
    <font file="LinLibertine_R.otf">Linux Libertine O</font>
    <font file="LinLibertine_M.otf">Linux Libertine Mono</font>
  </provides>

Is <provides> optional? If upstream includes two versions of fonts in either TTF or OFT, which one is suitable? Can both be included?

I plan to submit the Montserrat metainfo.xml to upstream but I would like to make sure the upstream guideline matches with Fedora Appdata guideline.
