Sorry to resurrect this old topic but I noted a corner case:

Imagine that in `MyPkg.jl` I do a

```julia
using Printf: @printf

```

then

```julia
julia> isdefined(MyPkg,:Printf)
false

```

and the `remove` would incorrectly (at least to me) suggest to remove `Printf`. Any way to programmatically check for unused deps?
