Thanks for proposing your help. To me the issue is not that much about the additional work it required when changing the doc values API, but rather about the discrepancy between the best practices as recommended by Lucene such as using doc values, consuming readers per segment and using points for numerics and the fact that Solr, which should be the greatest example of how to use Lucene, is not totally following them. I agree that things are changing fast sometimes and changing is not easy, but some of the things we are talking about here are more than 4 years old. I am also concerned that these things are accumulating, for instance I can already see how the integration of points is made harder by the fact that fields are supposed to support uninverting. And even if we decide that the new point fields do not need to support uninverting, then it will give users the feeling that these new point fields are not feature-complete, which would be a pity. On a similar note, I hope that we can prevent new indices from using legacy numerics as of Solr 7 so that the implementation can be completely removed in Solr 8 and points will be the only way to index numerics.
If we decide that Solr should keep supporting uninverting, I will accept it, but I genuinely think it would be better for Solr to eventually drop this feature and require doc values for sorting, facets and functions.
