AFAIK Effraim and me tried to make cargo pick up artifacts build in another package. I gave somewhen: cargo did not pick up the artifacts, due to much „magic“ which I was unable to understand and work around. One of the topics here are „features“ (like compile-time options), timestamps, exact absolute pathname, etc. All of this seems to go into some hash, which will determine which files will be rebuild. If anybody is interested, I could share the code of my last try. (Maybe the road to go would be to make cargo less strict here.

Yes, that would be nice.
