Does it have a choice?

I think we're thinking of different deployment scenarios. I'm talking about
something like:

   <Location /repo>
     DAV svn
     SVNPath /var/svn/repo
     ### bits that disallow access here
   <Location /repo/trunk
     ### bits that allow access to trunk here

IIUC, a request to /repo (or to /repo/something-not-trunk) wouldn't even get
to mod_dav_svn for processing because it fails the higher-level Apache authz

I'm not saying its a sane configuration, of course. But prior to
mod_authz_svn being created, it was through Apache configury like this that
we instructed folks to do their access control.
