Sorry, but I have not got your idea. Currently `org-modules' is just a 
list of packages that should be loaded with org.el.

It is possible to introduce some convention either in Org or in Emacs to 
add default action for a package. Then in addition to just loading a 
package (with no side effects) a set of functions should be implemented 
that loads and *activates* the package.

org-protocol may use approach similar to emacsclient-mail.desktop 
without advice:

Exec=sh -c "exec emacsclient --alternate-editor= 
--display=\\"\\$DISPLAY\\" --eval \\\\(message-mailto\\\\ 
\\\\\\"%u\\\\\\"\\\\)"

By adding another bunch of backslashes and a bit more complex shell 
command it is possible to avoid at least obvious issues with the command 
above.

Actually I have created

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=59743
Implement `command-line-args-left' for emacsclient --eval expressions

but I was too late to the party. The discussion in

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=57752
28.1.91; emacsclient-mail.desktop doesn't work for me

was stalled with no outcome.
