The idea is to keep associations between file types and handlers in a 
single place. Emacs does not have support of XDG handlers (at least out 
of the box) but pretends to have support of mailcap(5) database, 
https://www.rfc-editor.org/rfc/rfc1524.html "RFC 1524 - A User Agent 
Configuration Mechanism For Multimedia Mail Format Information". At 
least Debian provides a script that extracts supported MIME types from 
application .desktop files and adds this info to /etc/mailcap. I do not 
consider mailcap as a perfect solution, but there is nothing better 
within Emacs. I believe that configuring each Emacs package separately 
is even worse. Ideally it should work as a chain of responsibility: 
system-wide configuration in /etc/mailcap, emacs-wide adjustments, maybe 
package specific configuration.

I agree that is customary to set special PDF viewer to open citations. 
Have you considered another approach: to write a script that chooses PDF 
viewer based on file directory and make it system-wide handler? Then 
sioyek may be launched even by clicking on a file in file manager.

P.S. Alessandro, could you, please, response to mails using "reply" 
button. You messages lack of In-Reply-To and References headers, so at 
least thunderbird does not group messages into a thread.
