Thanks for the heads up on XDG support for Org protocol being broken.
I will amend accordingly.
AFAIR, it is not 100% broken. It is broken after some version of
xdg-tools (discussed in the bug report). So, not all the users will be
affected.
Notice that xdg-open parses files itself in fallback code only. I can
confirm that %F works with xdg-utils-1.1.3 in fluxbox session.
Normally xdg-open passes URLs to a handler specific to the running
desktop environment: kde-open5, exo-open, etc. Neither xfce-4.18 nor
plasma-5.27 passes URLs to %F. Either handler is invoked with no
arguments at all or error dialog is displayed instead. I would say, it
is a bug if some DE behaves otherwise and it may have consequences
related to security.
I am unsure concerning specific applications, e.g. Firefox-128 ESR
definitely parses XDG configuration itself. It is unclear to me what
method it uses to launch a handler, but it passes no arguments in the
case of %F.
P.S. I believe, org-protocol: handler should be merged with
emacsclient-mail.desktop instead of emacsclient.desktop
