Adrien Grand commented on LUCENE-8298:
--------------------------------------

I'd rather like not to add {{Bits#getMutableCopy}} and keep the {{Bits}} API minimal. Otherwise
+1.

>  Today once a document has a value in a certain DV field this values
>     can only be changed but not removed. While resetting / removing a value
>     from a field is certainly a corner case it can be used to undelete a
>     soft-deleted document unless it's merged away.
>     This allows to rollback changes without rolling back to another commitpoint
>     or trashing all uncommitted changes. In certain cenarios it can be used to
>     "repair" history of documents in distributed systems.
