if special "xdg-data" string is used for shared path,
we have no need for the wrapper any more,
since that shared path is also mounted within $XDG_DATA_HOME inside sandbox
@apol well, I believe it makes navigating and editing more easily, and better corresponds to idea of having all needed information to build the software in one manifest file.
The wrapper role is too minor for pushing it to a separate file.
I wish it wouldn't be needed at all, but we just have to keep it due restrictions flatpak has currently.
