Description
It would be very useful if Quassel had a client-core connection mode that use pure implicit TLS (with SNI).
This would provide multiple benefits:- Adds the ability to use any TLS load balancer or terminator (traefik/nginx/etc. with more nuanced configuration)
- Implicit TLS like implemented by other software is likely less failure-prone thus more secure than any ad-hoc TLS support
- Resists protocol fingerprinting
- Adds the potential to leverage things like mTLS (using a YubiKey/smartcard for auth), ECH or QUIC in the future
In theory it shouldn't also be that difficult to implement using already available libraries.

During my first experience with uno online, I did not foresee such a profound level of intrigue. Participating in games not only offers entertainment but also functions as an effective method for sustaining communication with cherished individuals, irrespective of their geographical location.
