libsvn_repos: understanding delta.c vs reporter.c

What's up with svn_repos_dir_delta[2] (libsvn_repos/delta.c)? It
seems to me like it does a subset of the functionality of the reporter
mechanism (libsvn_repos/reporter.c), with a completely duplicated
implementation. It also seems like it isn't used much: just in
svn_repos_dump_fs2, and in one bit of of the update report in
mod_dav_svn. Is its implementation actually semantically different
from the implementation of the reporter, or can it be reimplemented as
a wrapper around the reporter? Is the separation just for historical
reasons?

(There are also many places in the code that refer to
svn_repos_dir_delta[2] in comments, but which appear to be wrong
because it's actually the reporter that implements what it is
referring to...)
