opam switch import doesn't set invariant

[Khady]

tested with opam 2.1.2, I don't know what's the status with opam 2.2

I have an export file which contains

compiler: ["ahrefs-setup.git" "ocaml-base-compiler.4.14.0"]

I believe that it corresponds to the invariant of the switch, but I might be wrong.

If I do opam sw import --sw=. sw.export and opam sw invariant it appears that my switch has no invariant set.

I have to do opam sw import --sw=. sw.export --packages=ahrefs-setup,ocaml-base-compiler.4.14.0 to get things setup as expected.

I confirm, this is still the case with opam 2.2
