sometimes the removed device is re-added before the writes

RAID1 arrays don't have a chunk size, but if you ever convert
one to RAID5 you will need at least a small one >= 4K.
So round of size to a multiple of 64K.
This only affect Create, not "--grow --size=max". The latter
is too hard and with smaller returns.
