I assume that happened because you created the filesystem while the kernel
was running with 64k pages and btrfs used that to adjust the sectorsize.

I don't think switching back to 4k pages would prevent you from using
btrfs, you will just have to recreate your filesystem.
I also don't think we can cover each and every usecase. However, seeing
the problems introduced by switching the page size, I'm surprised at all
this change was made without any previous communication.
