When a `variantFilter { ... }` is used in Android projects, AGP does not
creates some variants but still creates the source sets which would be
related to those variants.
For source sets that are not included into any compilation, the stdlib
module added by default was kotlin-stdlib-common, and it was added to
the `api` scope.
But AGP checks the `androidTest*Api` configurations and
if it detects any dependencies in them, it reports deprecation warnings.
However, we have plans to prohibit unused source sets at all as they
have no reasonable use cases. So the fix is not to add the stdlib by
default to source sets that participate in no compilations.
