OCS/ECS don't care too much about alignment, needs to be 16-bit obviously. AGA introduced 32-bit access, so bitplanes need to be aligned likewise.
I suppose 64-bit is for emulation optimization. 64 KiB sounds very strange...

Modern x86 CPUs use 64-byte cache lines, so 512-bit alignment may be of advantage for emulation - provided emulation memory gets aligned, too...
