That makes sense -- we'd also want to encourage projects to note their
project name someplace central; having a namespace registry helps to
avoid collisions, and also helps to advertise the projects that derive
from notmuch :)

maybe update the wiki for that?

That said, if a given property is concretely useful, i don't want to
have it languish permanently in the x-<project>- namespace, or to force
users to adopt that particular MUA to use it -- i'd like to make it
available to all the notmuch-derived mail user agents.  Maybe that
happens only when the feature gets added to libnotmuch itself?  How do
we incentivize projects into getting that kind of widely-useful feature
into the libnotmuch mainstream instead of having it as a differentiating
factor for their specific MUA?

how should we think about managing these parts of the ecosystem?

cool, this sounds super useful.  if you have a chance to write up how
you're generating/selecting this extract, i'd love to read more.

Thanks for the pointer, i'd missed that thread back in February.

I agree that there's sufficient interest to take this use case more
seriously.

Yeah, that's probably a good idea.  Is it asking too much to ask you to
update notmuch.h as well when you resubmit this series?

Thanks for helping make notmuch better!
