Most early Sun equipment required 512 block size also.
Not that I am casting doubt, but I am unaware of anything that required 2048
block size for optical devices.
If you have a workstation or server that required 2048 block size for optical
media, please share!
That is the great thing about this list, I learn new stuff, all the time.

That's an excellent feature that I'm sure would come in handy, especially
if it can emulate a CDROM with a 2048 block size. That'd be super-helpful
on an SGI, and would probably make the mind-numbing 'inst' operations take
a little less time.
