The backup tools need to also get the LSN from the pg_stop_backup and

There is a function for that.
They also
need to make sure that they have all of the WAL files between the
starting LSN and the ending LSN. Doing that requires understanding how
the files are named to make sure there aren't any missing.
There is not a function for that, but there could be one.
A function would be nice, but tools often cannot depend on the database
being operational so it's still necessary to re-implement them. Having
a sane sequence in the WAL makes that easier.
