What about deploying the wrapper hooks into all repositories, with
permissions set so the user cannot replace them?

Then the user cannot run arbitrary code as www-data.

I guess the permissions would involve the wrappers being owned by root,
mode 755, and the hooks directory would need +t, or otherwise
restrictive permissions to prevent the user from deleting the wrappers.

Still, I can see that it's not a wonderfully elegant solution.

Where would you envisage a potential exec helper being configured? I
suppose in httpd.conf and/or on the svnserve command line?
