Yes. Usually I recreate test_dev after config was updated.
And I tend to agree that this may not be suitable for others.
In order to fix original issue I'll remove block_size argument from
_scratch_mkfs_sized and pass MKFS_OPTIONS instead. This will be valid
change because currently no one pass block_size to _scratch_mkfs_sized anyway.

Off course. But I meant to say that this arch may use different
block_size by default.
