In the Julia v0.7/1.0 package manager, is it possible to specify a specific branch or tag for a dependency that is only used in the extra / target section?

You can, however, use a custom project for what you wanted to do. See e.g. [https://github.com/fredrikekre/Sandbox.jl](https://github.com/fredrikekre/Sandbox.jl) where I am trying out using a `test/Project.toml` and `deps/Project.toml` environment instead of using `[extras]` and `[targets]`.
