This might be a silly question, but can I not just reformat my Jolla with something more sensible?

There's less of them now (after a metric assload of backported patches, AIUI) but I'm pretty sure it's still non-zero (see https://github.com/nemomobile/libcom...a02b61a74a3192 for one such recent example that I'm pretty sure was exacerbated by FS issues..)

is there any glimmer of hope that btrfs will be removed in the future?

Especially LVM thin pool would get you basically the same COW snapshot functionality as in btrfs, with the important difference of being rock solid, stable and generally sane.

Is it already known if the tablet will use btrfs too? I hope not.
I already had to rebalance my filesystem twice, with never more than 7 gigabytes of space actually used on my Jolla phone. And since there's no warning whatsoever that the allocation space is going to be full, I had to add a "btrfs fi show" to my maintenance routine (which is not that painful to do, but still, I would like to not have to do it).

I have not a problem with btrfs per se, it is its use in mobile: on a pc you can make the system auto-perform balance operations, on mobile less easy so for battery management issues etc., and the limited amount of space makes it easier to run out of allocation space.

Let's not be too fatalistic: surely mostly this is fixable, either by patching BTRFS / the kernel, or perhaps by writing a daemon or something that runs a balance every month or so when the phone is plugged in during the night...
