connections to 127.0.0.1 no longer possible

No longer allowing connections to 127.0.0.1 at all (#10419 (closed)) is a huge disadvantage.

Users using the i2p web interface can no longer use it using Tor Browser.
Users wanting to visit their own hidden service using 127.0.0.1 won't be able to do so anymore.

And what will they do? Using a regular browser. And being worse off.

Can you allow connections to 127.0.0.1 will still defeating fingerprinting issues (#10419 (closed)) please?
