Well, the current specification surely doesn't define anything else and is already over a decade old. So what would be the odds that they add a different blocksize variant_now_ AND still call that SM3-something?
I just got a note from a cryptographer who said there were discussions last year about a future SM3 with 512 bit output.
Given that, why not plan ahead and use sm3-256? Is there any downside? Is the cost any more than 4 bytes in some source code?
