Very nice project.

I would like to move away from WhatsApp for privacy reasons and out of principle.

Could I use this to set an auto-reply message to users contacting me, redirecting them to my new messenger e.g. Signal?

If you don't mind having a phone (or emulated phone) being on at all times running the whatsapp native app, and if you make an IRC bot that automatically replies to things, yes that's possible.
