Fedora reawakens the hibernation debate

The API GNOME is using appears to have two methods, "CanSuspendThenHibernate" and "SuspendThenHibernate"
https://gitlab.gnome.org/GNOME/gnome-settings-daemon/comm...

In that code it looks like GNOME does "if (CanSuspendThenHibernate) { SuspendThenHibernate }" which, you know, seems reasonable.

If the implementation doesn't know whether it can SuspendThenHibernate (without crashing, to some degree of certainty), I'd say CanSuspendThenHibernate should return false.

If the only way to know whether CanSuspendThenHibernate is for a user to try to hibernate a bunch of times themselves and see if it fails, then the SuspendThenHibernate feature doesn't exist for all practical purposes - better for CanSuspendThenHibernate to always return false, or maybe always return false unless it's been manually enabled through some system-level configuration file.

If CanSuspendThenHibernate can't be trusted then it becomes impossible to ever enable the feature through system-level config or hardware quirks, because GNOME and others would have to ignore that API entirely. Better for everyone to use the API, and then fix the API (even if the fix is a config option, the option should configure the canonical API, rather than configuring only certain apps or certain desktops).
