Adrien Grand commented on LUCENE-8483:
--------------------------------------

Can we somehow avoid the FakeWeight in ValuesSourceScorer? They look created 
via a FunctionScoreQuery most of the time, so we should have a weight object 
available?

I'm also wondering whether we should consider another name: FakeScorer used to 
be a hack since it didn't really implement the Scorer API, while FakeScorable 
is now a pefectly legitimate implementation of Scorable?

> Enforce that Scorer cannot have a null Weight

> Follow up to LUCENE-6228.  All Scorers that were passing null as their parent 
> Weights can be replaced by Scorables, so we can now enforce that Scorer must 
> not have a null Weight.
