To be concrete, suppose the package `Foo` has an extension `Ext` which depends on `Bar` and `Baz`.

Then it may be nice to let

```julia
pkg> add Foo[Ext]

```

be a shorthand for

```julia
pkg> add Foo, Bar, Baz

```

(thus allowing the fact that `Ext` depends on `Bar` and `Baz` to be an implementation detail).

And further, it may be nice to let

```julia
import Foo[Ext]

```

be a shorthand for

```julia
import Foo, Bar, Baz
const Ext = Base.get_extension(Foo, :Ext)

```
