The spec says that additional non-standard fields should be prefixed with something like X-Gnome- , although it doesn't appear to be mandatory:

https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s12.html

I agree that it's probably a good idea to get a desktop interested in the idea before focusing on the specification. If you can get a desktop to implement it even as a non-standard field, I imagine it would be quite easy to get applications to use it.
