Since CCS0 (spec, not module) is about to go into core
<https://rt.perl.org/rt3/Public/Bug/Display.html?id=118959>, and this
becomes canonicalised as best practice, I'd like to know which
considerations went into the design of the spec as I have the feeling
that it's not as good as it could be.
Especially, how does it compare to prior art, e.g. the formats
described or used by Debian, specfiles, LTjake, hex, hanekomu,
rgiersig, rsavage or cdolan? How does a user extend the format, taking
advantage of the machine readable aspect, to add metadata using the
vocabulary established by ascope?
