So do lots of other features, including suspend to RAM.  Not using
hibernate by default could be a good idea, but disabling it goes a bit
too far IMO (and by "disable" I mean remove it from the GUI entirely).

Personally I don't care about that.  It's slow on every OS, and if it
works you don't really need to care about the time.

Except that some hardware runs out of battery very quickly (anything
less than a day I consider "quick"), even when you "just suspend".

It's not confusing when using a working hybrid suspend...

I think most "hibernate bugs" are related to the lack of (re)storing
state in hardware drivers.

Fixing that for most of the kernel & drivers will require a lot of work.
I wonder if it's possible to do a static source analysis over the linux
device drivers, and get a list of potentially problematic drivers for
suspend out of that?
