See `org-open-file' IN-EMACS argument - we may use different handlers
to open file links. Currently, IN-EMACS can be 'system or 'emacs. But
nothing stops us from adding more options.

This will cause major issues when trying to export such links.
Except for HTML export that utilizes `org-html-link-use-abs-url', but
only for relative links.
Why not make [[hyper:/README.org]] use the "default" hyperdrive the
Org file belongs to.

IMHO, it is too specific for Org core.
What we might do is allow setting :follow function for file: links. We
generally aim to remove hard-coded link types from `org-link-open',
exposing them to `org-link-set-parameters'.
For example, see WIP patch where we expose setting id: link properties:
