Uhhhh.... Not at this scale. Thats what I thought about one of my previous open source projects. I was a naive highschool kid back then I thought open source is great. Let anyone use it. Yay! The one fine day someone raised a PR (this was back in 2012 when CI was not very common). It looked OK and I merged it. The following weeks had me battling issues with people using the library. Eventually I abandoned the project cause I didn't have the time/funds/motivation to continue working on it and there were better solutions available on the market.

Perhaps it is a sign the project is too large and need to be broken up in more manageable parts?

In my case the problem was: High school kid who is good at coding != software engineer (there are many other nuances to SE, including team management/planning/etc.)

In Cairo's case: Waaaaay too many projects depend on Cairo as a dependency either through GTK+ or otherwise. You will be breaking heaps of backwards compatibility.
