I think, it might be helpful to mention the `browse-url' package in the 
docs for the :follow property of `org-link-parameters'. Writing code to 
launch an external application may be tricky, so it is better to 
delegate the task to existing utilities.

Subject: [PATCH] ol.el: Recommend `browse-url' to `:follow' links

* lisp/ol.el (org-link-parameters): Recommend the `browse-url' function
for calling external protocol handlers in the docstring.

This is indirect follow-up of the
https://list.orgmode.org/3218434.44csPzL39Z@linux.fritz.box/ thread.

Maybe better add this to "A.3 Adding Hyperlink Types" section of the manual?

If you you believe that the (info "(org) Adding Hyperlink Types") 
section should be expanded then a complete example is necessary, some 
ideas may be picked from

https://orgmode.org/worg/org-faq.html#mailto-links
https://orgmode.org/worg/org-faq.html#mid-url-handler

While the manual section and the `org-link-parameters' docstring as the 
reference may be cross-linked, some note on `browse-url' still may be 
helpful in the latter.

I believe that examples like yours really belong to the manual, not to
the docstring. Your example is the shortest possible way to define a new
link type as opposed to writing a whole new library - something rather
hard to achieve for less experienced users.

So, I suggest to
1. Put your example to the beginning of "Adding Hyperlink Types" section
   of the manual as the simplest way to define a new link type and
   use ol-man as a more complex example if more features are needed.

2. Refer to (info "(org) Adding Hyperlink Types") from the docstring of
   `org-link-parameters'.

WDYT?
