Sure, I suggested that each desktop had its own lib so gnome-exec would 
be replaced with DESKTOP_LIB=libgnomedesktop.so.0 or whatever, and any 
library named in $DESKTOP_LIB conformed to the same interface.

I'd rather have standards for each different technology though rather 
than letting each desktop reinvent the default-app (or whatever) wheel. 
But this seems like a good temporary compromise in the face of limited 
manpower.
