One of my machines runs root on ZFS via DKMS. I will grant that it is annoying, and it used to be worse, but I don't think it's been quite as bad as all that for a very long time. I would also argue that it's more acceptable for testing actively developed stuff that's getting the bugs worked out in order to work towards mainlining. That said, I vaguely seem to recall that bcachefs ended up involving changes to other parts of the kernel to better support it; if that's true then DKMS is likely to be much more painful if not outright impossible. It's fine to compile one module (or even several) against a normal kernel, but the moment you have to patch parts of the "main" kernel it's gonna get messy.
