CSS Intrinsic Sizing
Extends the CSS sizing properties with keywords that represent content-based "intrinsic" sizes and context-based "extrinsic" sizes, allowing CSS to more easily describe boxes that fit their content or fit into a particular layout context.
CSS intrinsic sizing is now on the Microsoft Edge backlog. You can track status changes at https://dev.modern.ie/platform/status/cssintrinsicsizing/

Considering responsive design is pretty huge (and has been for some time now) not having intrinsic sizing is somewhat archaic. It should have been added a long time ago.

Really handy when you want to scroll flexbox items that live inside a flex container. Without these values it is not possible to solve problems like this: http://codepen.io/benfrain/pen/NPKzXM

There's no reason not to have CSS Intrinsic sizing given how important they are to maximize the use of Flexbox, Flexbox 2 (upcoming0, and CSS Grid layout modes.
