Pkg.activate is not enough for forcing correct environment

This is perhaps a bit of a drive-by comment (I haven't used the package myself), and perhaps it has been discussed before but Pkg.activate is not enough to make sure you use the correct environment. Here is one example:

$ JULIA_LOAD_PATH=/tmp/Project.toml: julia --project=. -q
julia> Base.active_project()
"/tmp/tmp.ovN3Dd5eeE/Project.toml"

julia> Base.load_path()
4-element Vector{String}:
 "/tmp/Project.toml"
 "/tmp/tmp.ovN3Dd5eeE/Project.toml"
 "/home/fredrik/.julia/environments/v1.6/Project.toml"
 "/opt/julia/julia-1.6/share/julia/stdlib/v1.6"
