This is indeed a common use case.

So, if I've got this right, you add the svn:template property after
creating the template, adding it, and committing it to the
repository. However, if you want to modify the template, you remove
the property, commit its removal (requiring a special hack to detect
this case?), make your changes + restore the prop, and commit again.

This makes the editing process awfully clunky...
