Recommended transition to LazyArtifacts

Internals & Design
1

Is there a recommended path for packages that use Artifacts to transition from

using Pkg.Artifacts

to

using LazyArtifacts

I’m a bit confused about how to modify Project.toml so that it works with both the 1.5 and 1.6 versions of Julia

If you need backwards compatibility with v1.5, then importing just Pkg will work.

Does MixedModels import Pkg?
