I have nothing against adding org-capture to Emacs core, but I think 
org-protocol should be just obsoleted. Since `server-eval-args-left' has 
been added to emacs-30, hacks from org-protocol have a little value. The 
new feature allows to implement handlers of URL schemes in a safe way 
and to avoid backslash hell similar to emacsclient-mail.desktop.

A tiny package may be created for convenience to have single .desktop 
file for all URI protocols (mailto:, org-protocol:). Leaving aside 
tricks with --display, handler should be like

      emacsclient --eval "(handle-url)" %u

or %U for multiple URLs. Packages just register supported protocols in 
e.g. an alist and the dispatcher calls a function for matched scheme 
with an argument from `server-eval-args-left'.
