runtimeOnly configuration for variants

I’m trying to break down the dependencies of a project producing a monster-jar using feature variants, and I noticed that for each variant xxx we get only xxxImplementation and xxxApi configs.

https://docs.gradle.org/current/userguide/feature_variants.html#sec::declare_feature_variants

While that makes sense from consumer point of view, from producer point of view it would be nice to make a distinction between implementation and runtimeOnly for the variant.

Or am I missing something?
