Isn't it really simpler to use RSA and DH and ECC in series ? Why choose ONE ? There is no good reason for that.

1. Silly Elloi, you can only use DH when both parties are online. And of course RSA and DH have similar failure modes -ie factoring. ECC may have similar failure modes with RSA/DH, I'm not sufficiently informed. A chain of different kinds of padlocks might look strong but they all dissolve in aqua regia.

Looks like PSYOP to me.

That's an interesting explanation I hadn't considered in my previous post. (Sort of like putting a stone facade on that new iron bridge because some folks don't trust the newfangled iron bridges.) However using such keys are a heavy practical cost for PSYOPs.
