sounds interesting for preventing EM side channels for computers processing sensitive data…

but for WiFi it could even be beneficial if it was also reflecting to some extent instead of fully absorbing, because it would make MIMO more effective

Possibly, but sometimes reflection isn't your friend. I remember having issues shooting 5ghz links between sheet metal buildings and having to turn the signal way down, or echoes started causing interference.

Just the right amount, which is the hard part.

And that was with fairly narrow directional antennas. With an omni it gets even messier.
