Indeed. This extension change for many could look like nothing burger, but if you think a bit about the multiple applications it can be used you realize how powerful it is. Including for adding privacy.

Example: I setup a lnbits on a vps. I setup another one on my home node or whatever other cloud server, it doesn't really matter where is located. I can even connect them using Tor or Tailscale.

Then setup public LNURL that behind will have a split formula in multiple parts. Nobody will know or could find out where are actually going those sats.

Also the posibility of changing the funding source for LNbits could create endless scenarios.

Very powerful extension!
