For 2 I think I wasn't clear in what I was looking for.
Instead of using cargo for everything, being able to use
pkgsrc defined packages for crates would be good. This used
to be how I approached crates somewhere else, but the more
I learn about recent cargo and more specifically the way it
is used in pkgsrc, the more the way it is done now seems to be okay.

There's still so much duplication going on, but splitting this up
was always annoying (recursive deps, etc).
