Yes, I believe that the Syncthing protocol doesn’t bring security concerns, but some people may wish to hide their IP and device info from being “exposed”. I know Syncthing has some data collection which you can opt out of.

I think a benefit of this post is to show that you can self-host applications and use the I2P network to connect to your services while bypassing issues like CGNAT. Hopefully, it helps spark ideas to host more services on I2P as well.
