Prior to this change GTK_USE_PORTAL was unconditionally set to "1". For this to not break things you have to have some sort of portal implementation in extraPortals. Setting GTK_USE_PORTAL in this manner is actually only useful when using portals for applications outside flatpak. For example people using non-flatpak Firefox who want native filechoosers. It's also WIP for electron applications to support this.
