About sponsored bugs: I remember @KaiRo wrote long time ago about how people used to take small bugs and not the real important (and difficult) ones. I don’t know if it’s still the case.

Then just put the big ones up and add the small ones at stretch goals.
What is the biggest and most expensive feature/bug that is not being implemented or being implemented too slowly because of lack of resources and what is the cost of that bug/feature? $1 million? 10, 100? Would it be a the Rust build? How much for the completion of ES2015? What would be the cost of something smaller like CSS Grid Layout? I would love to **vote with money** on these features.
