Some Debian packages depend on gnome-www-browser so please add Provides: gnome-www-browser . I guess you could also add Provides: x-www-browser but I see that fewer browsers do that.

You can see which packages provide and depend on this virtual package with:

apt-cache showpkg gnome-www-browser

For instance, cinnamon-desktop-environment depends on gnome-www-browser and it doesn't have the chromium-browser name in the alternates (it has Debian's chromium name instead).
