Why? I think it makes perfect sense to focus on a mesh routing protocol and make anonymity something optional that you can lay on top of it. No reason you can't run a Yggdrasil network and have an I2P network within it. This way there isn't as much of a performance hit for communications that don't call for anonymity, and anonymous peers can be established without being on the clearnet.
