It is indeed unused, but given that it exists and the callers set it
appropriately it could be a pretty valuable debugging aid when attaching, or
adding logging, to TeardownHistoricSnapshot. Compilers are smart enough to
take care of this for us so there seems to be little value in removing this
(apart from silencing AI tools but that's not something we optimize for).
