As of https://gitweb.gentoo.org/repo/gentoo.git/commit/sys-apps/flatpak?id=f1fbb39938ea84137269e202270a2b33462d9cd8 sys-apps/flatpak depends on sys-apps/xdg-desktop-portal only, which needs an implementation to work. I think this could be done either by setting them as dependencies or as a post install message.
*/xdg-desktop-portal-{kde,lxqt,gnome,gtk,wlr} packages all depend on xdg-desktop-portal, so this would create a circular dependency unless PDEPEND is used. I don't think it is necessary to make a dependency here, rather it creates potential for unwanted/unsuitable portal implementation deps for someone installing sys-apps/flatpak without pre-existing portal-* package. It is up to the DEs' meta packages to provide the facilities for flatpak integration, and people who "go minimal" will be used to choose the portal impl on their own. For them, a postinst message can be provided, otoh why spam everyone else with something they get as a dependency of their portal-* implementation. So maybe it should be made on the condition of none of the known implementations being present.
Oh I'm not using any desktop package, so I was surprised when --depclean tried to remove xdg-desktop-portal-gtk and I thought it was an unintended side effect, but that makes sense now. I'm voting in favor of the conditional postinst message, after all a portal implementation is required and this seems like a nice reminder.
What do others think?
Also, at least for Qt this change was added to fall back to native dialog in case no XDP impl available: https://invent.kde.org/qt/qt/qtbase/-/merge_requests/177 https://bugreports.qt.io/browse/QTBUG-98988 > Add QXdgDesktopPortalFileDialog::useNativeFileDialog() > Fallback to another file dialog implementation when XDP is inaccessible
