We'd like to see the CSS limit increased from the current 50K to 100K.

Background - we're automatically converting sites, including all their look and feel to AMP. Many sites have 3-400k of CSS which we prune down to only the rules that are used on the page. This Typically yields between 30 and 80k of CSS.

This means that on the larger files we need to very aggressively optimize the CSS size by rewriting extensively which is a) computationally expensive, b) tends to break things in unexpected ways and c) means we're dropping /*! comments containing rights info which puts us out of license compliance. Increasing the limit to 100K would make all those issues go away for many publishers who are converting existing templates.

Here is an example page that's right up against the current limit https://cdn.relaymedia.com/amp/www.niemanlab.org/2016/08/that-friends-and-family-facebook-algorithm-change-doesnt-seem-to-be-hurting-traffic-to-news-sites/
