We still have disk space accounting changes coming for erasure coding, and the changes won't be as strictly backwards compatible as they'd ought to be - specifically, we need to start accounting striped data under a separate counter in bch_alloc (which describes buckets). A fsck will suffice for upgrading/downgrading, but since erasure coding is the most incomplete major feature of bcachefs it still makes sense to put behind a separate kconfig option, so that users are fully aware.
