Yes, but it can fail (it doesn't catch external moves and the user can
limit the registry size to save memory).  See nnregistry.el for an
example of how to use `gnus-refer-article-method' with the registry.  So
maybe the org-mode Gnus integration can use gnus-refer-article-method,
if it doesn't already, and let the user decide if the registry should be
part of the refer search path.
