I'm not a user of either :cache or :results replace but multi-block return, if implemented, will likely require some non-trivial work to be incorporated smoothly. Returning just a single block by default will keep it safe for general users. But I do find it suspicious when some output is produced and yet not submitted into the buffer where evaluation results are supposed to go. And Org seems to be able to handle this very neatly. >> while simply hiding empty blocks, if any, for convenience. >> >> Note that currently, when “output” is specified, “values” is simply >> lost, and vice versa.

If not, warn user to update SLIME. WDYT? For now, I just delayed activation of the feature in Org until a certain future SLIME version. In my SLIME patch, it's handled more subtly, using supplied-p optional argument, a check that can be dropped once Org 9.3 becomes unsupported.
