Not sure I understand what you mean. But yes, the desktop entry spec would
need an update... The MimeType key needs to be added to Table 3. Action
Specific Keys. I also propose updating the example desktop entry file to
display that behaviour.
The syntax itself for mimeapps.list would not require an update as it's
just a "list of strings", although I don't think mimeapps.list actually has
a spec anywhere.
