I have on occasion found myself wanting to supply a formula to express timing functions for example when I wanted to perfectly invert another timing function to implement an [accelerated expanding reveal](https://developers.google.com/web/updates/2017/03/performant-expand-and-collapse) animation. We ended up approximating this inverse scale with a [generated linear animation with lots of keyframes](https://developers.google.com/web/updates/2017/03/performant-expand-and-collapse#step_2_build_css_animations_on_the_fly) but it could have been expressed as a single formula. Could supplying a formula solve some of these other express-ability use cases as well?
