Grepping for queue is not clever idea, sorry.
1.1.3 has topology support, 1.2.0 adds 1MiB default here.
Run luksFormat --debug and you will see topology info read from kernel:
# Topology: IO (512/0), offset = 0; Required alignment is 4096 bytes.
512/0, offset = 0 means min io size / opt io size and offset from sysfs.
For ssd it should be surenly not 512 but something like write block.
