As I explained, there is already a default handler in every major
back-end.

However, Org needs to tell links with a type from the others (internal
links). This is what `org-add-link-type' is for. This has nothing to do
with export.

To put it differently, when Org encounters a foo:bar link, there are two
options. Either "foo" is a registered link type, or not. If the former,
Org tries to use whatever export function was provided, or fall-backs to
the default handler. In the latter, Org considers it to be an internal
link. Since there is probably no #+NAME: foo:bar, <<foo:bar>>
or * foo:bar in the document, the export process returns an error, by
default.
