Slidge v0.1.0-RC1: An XMPP to IM walled gardens (Signal, WhatsApp, and 6 others)

For no reason besides having been usable enough for my own needs for a few months now, I tagged the current status of my hobby project a "v0.1.0rc1".

It's an XMPP server-side component that acts a client to various instant messaging chat networks, letting you use your favorite XMPP clients to centralise all your chatting needs. Some sort of "multi-device, multi-protocol chat 'app'". It supports

Happy to hear any feedback about it, or why it's a bad idea to use XMPP because it's obsolete (it's not), or why it's a bad idea to use these walled gardens anyway (spoiler: I agree).
