looks like this just exposed the existing issue of extra-deps missing from index #1521 get silently ignored

It should indeed fail and we were discussing about it in #1858 :)

While this indeed could be covered by such extra-deps checks, I think it's best to special case this one during target parsing. That way the error message can be clear. I've made that change here 7262dd2
