Presumably merge-tree wants to serve a low-level machinery that
gives reliable reproducible result, we may want to keep the
configuration variables we read as narrow as practical.  The
default_config() callback may still be wider than desirable from
that point of view, but I guess that is the most reasonable choice?

Thanks.
