Dawid Weiss commented on LUCENE-8334:
-------------------------------------

Yeah... I look as much as my time permits, which isn't too much. :( What you 
mention is actually what we do: I wrongly thought you removed the public 
qualifier from the class (as well as the constructor); looking at the diff only 
confused me. LGTM!

>  The SegmentCommitInfo passed to the segment reader is mutated concurrently.
>     An instance obtained from SR#getSegmentInfo() might return wrong delete 
> counts
>     or generation ids. This ensures that the SR will use a clone internally 
> while stil
>     maintaining the original SI since it's needed inside IW for maintainance 
> like
>     accessing pooled readers etc.
