I am mostly going to address user confusion about mailcap - (1) a number of people are using DMs that rely on FreeDesktop and xdg-open; they get surprised when .mailcap is used - I've seen a number of questions in IRC/Matrix and on reddit related to how Org mode opens file links; (2) Emacs' mailcap does not implement the specification fully - only a subset of mailcap format is obeyed. So, I do not feel that Emacs' implementation of mailcap support is a good default for most users. > Did you intentionally mentioned "xdg-mime"? No. I meant xdg-open. > ...

Yes, but mailcap is not documented in Emacs manual. FYI, I first heard that .mailcap files are a thing when I encountered org-file-apps. > ...

There are problems with mailcap.el and there might be problems with Emacs media type configuration. I prefer xdg. > Is it necessary to modify Org? Maybe an alternative is to add "xdg-open > %s" for */* to `mailcap-user-mime-data'. Do you mean changing the default value of `mailcap-mime-data'? >> I believe that xdg-open issue has been fixed by you in >> https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=5db61eb0f >> org.el: Avoid xdg-open silent failure > > I am still not really comfortable due to the strategy to start external > processes diverged from methods used in browse-url.el.
