Certificate based Authentication for GUI

[bigops]

Are there any plans to implement Certificate based authentication for the GUI?  As OPNsense already has a USP for having 2FA natively in the system a Certificate based auth would be a worthwhile addition to the security framework and would be useful in a few unique security frameworks which I had come across where currently the solution is to deploy a VPN for GUI access from outside, but a VPN has its own drawbacks due to the unreliability of the transport.
