Of course you are not the only one. But the real answer was to be found
in another random stackoverflow forum:

When you have 512 octets logical sectors and 4096 octets physical
sectors, you really have eight logical sectors in a physical one, it
matters to align the small ones inside the big ones.

But with blocks of flash memory, there is not constant nor regular
mapping of sectors to blocks, so the information about the block size is
not useful outside of the disk controller.
