Yes, that was my conclusion as well. It would seem the pro= blem is really just because (in this case) we have org and org-plus-contrib= as two packages in the org/elpa repos when really here should just be org = and org-contrib. This would then mean if you have a package which depends o= n org, all is good and if you want the contrib stuff, you just install an a= dditional package with just the contrib additions.=C2=A0 Would also make th= ings easier with 'helpers' like use-package.=C2=A0

IIUC, package.el figures out dependencies by package name, not by th= e
features it provides.=C2=A0 So, I think the answer to your question is no.<= br>
