I'm seeing a lot of descriptions having a features list and can't help but wonder if it wouldn't make sense to have them formalized. e.g. the windows store works this way. It'd allow clients to render features lists in a consistent place/format (and also allow appstream metadata to better feed into windows store releases)

<features>
<feature>crash</feature>
<feature lang=de>flugzeug</feature>
<feature>memleak</feature>
</features>

or some such
