Anyone else running a mesh router of Tor, I2P and Yggdrasil?

I have been experimenting with different privacy and networking tools and somehow ended up setting up what looks like a small mesh network involving Tor, I2P and Yggdrasil. I am not entirely sure what I have built, but it seems to be working.

Here is what I did:

1. Installed the Tor package and configured it as a SOCKS proxy.
2. Installed Yggdrasil and connected it to a few nodes that only allow Tor connections.
   You can find the list of Tor-enabled Yggdrasil peers here:
   https://github.com/yggdrasil-network/public-peers/blob/master/other/tor.md
3. Installed i2pd and configured it to run as a mesh router through Yggdrasil.
   Configuration guide:
   https://i2pd.readthedocs.io/en/latest/tutorials/yggdrasil-only-mode/

Now all three seem to be running together in some way. I can see network activity across them, but I am not completely certain how the traffic is being routed or what the overall effect of this setup is.

Has anyone else tried combining these networks like this?
Is there any practical benefit or unique purpose for linking them together this way?
Could this be considered some kind of higher-level or experimental overlay network?

I am mainly interested in understanding what this configuration might actually be doing under the hood, and whether others have tested similar setups or noticed interesting behavior.
