Certificate authentication with out of the box REST functionality

Hi, With the current REST module it's possible to add authentication using a certificate. Is it going to be easier to use certificate authentication with the out of the box REST functionality in Mx7?

Authentication using certificates is on our roadmap. In true agile fashion, we aim to release features in small increments. We have a number of rest features on our roadmap.

What is the exact use case you need to implement around certificates and rest?
