Hey Eric! :)

Which do you think has influenced CSS specs more in the last few years: engagement between working groups and developers, or industry trends like CSS preprocessors illustrating demand for features? (Or has something else entirely been the biggest driver?)

I feel like preprocessors have been a big influence. Things that the WG has rejected for years (even decades), like variables and even logic, are now finding their way into the specs because they were implemented in preprocessors, and lots of authors used them. I love preprocessors for that.

The other huge influence has been, just as with everything else, mobile. A lot of things that would have been nice in the past were made critical by mobile. Responsive images are just one example of that. There are similar things happening in CSS, such as more powerful media queries.
