However I do not mind to have an easy way to delegate URI from :export

Just make the :export function return nil.

I missed this feature, but anyway it does not work as expected.

  (org-link-set-parameters "tel")

or

  (org-link-set-parameters
   "tel"
   :export (lambda (_path _descr _backend) nil))

strips link type and exports links as e.g.

  \href{321}{call}

"tel:" is missed. Each backend has its own hardcoded list of blessed link types to preserve link type/protocol/scheme:
- LaTeX: "http" "https" "ftp" "mailto" "doi"
- HTML:  "http" "https" "ftp" "mailto" "news"

Actually I had in mind more flexible delegation. :export functions should be able to alter URI, attributes and to provide description if it is missed, but did not care if '<a href=""></a>' or '\href{}{}' should be used.

Easy way to add protocol/scheme should include :follow with `browse-url' as well.
