If a URI seems percent encoded, but only uses %25, %5B and %5D as escape
combinations, there is a high chance that it is Org-encoded, and
therefore uses a deprecated syntax. We could send a warning to the user
in this case; they might want to clean the URI.

OTOH, if there is %28, or %29, we are sure it isn't Org-encoded, and
therefore, the percent-encoding was intended right from the start (like
in your Wikipedia link).
