Idea: we can drop the +components/variations dependency in components/previews/{core,content} (ie, remove uses of  variations::testing::ClearAllVariationParams()) if we can migrate unittests to ScopedFeatureList instead.

Consider migrating trials to FeatureApi and using ScopedFeatureList?

Good idea, I will discuss that with Ryan

The new features we add, we add as Feature API. We've avoided migration because we didn't want more config files for different versions.

You shouldn't need to have seperate configs.  You should be able to just add the enable/disable features block to your groups, and the same config will work with both versions of code (as long you keep group names that work).  But up to you based on how long you expect to continue running the trials.
