You still haven't answered the question as to the specific use case.

It is already abstracted in ArtifactMetadataSource interface

This interface cannot be exposed via the embedder, if you want to  
return an ordered Set of versions that's fine.

, so if
you want to add the index as another source right now you'd just need
to make a new implementation.

I expect anything you are working on will be put in a feature branch  
in the sandbox for review so I will look at it as the embedder  
interface already needs to slim down and I'm adamant about not  
exposing any internal API or structures, in particular anything to do  
with maven-artifact because anything dependency related has to move  
to a graph structure as what is present is fraught with problems.

So in your particular case a query by groupId+artifact id should  
yield a set of versions. So exposure of ResolutionGroup,  
MetadataSources or anything else.

If this is for releases which is probably what the you want there are
no inconsistencies and the index is actually far more reliable.

If you want up-to-date snapshots then that's a different story but I
can't see the vast majority of people doing production development
work being interested in that.

If you want snapshot support then it would have to be dynamic as the
index is only updated on a daily basis.

This should be abstracted anyway because in the future I think
leveraging the tiny index that can be pulled down locally would
provide an artifact resolution mechanism that is far more reliable
and an order of magnitude faster.
