if libnotify is deprecated, document this within the project's documentation
I was looking at libnotify and the apps that depend on it as a "concerned citizen", since many apps still depend on it, even though as I understand it has been superseded by functionality in GIO. This creates a lot of nasty bugs since libnotify is a blocking API.
In my opinion, again, only as a concerned citizen, if libnotify is deprecated, the maintainers should clarify this in the documentation, and keep it in pure maintenance mode or EOL it. Or if folks want to keep it going under a new major release, the officialdom of it being a GNOME project should be dropped and that should be clarified in the project's documentation.
