More developers (who don't know c (good enough), but are proficient in go) who can contribute to the compiler code long term (and improve the transpiled compiler). Other reasons would interest me as well.
Yes, I doubt it too. But are they interested in contributing to the go compiler if they don't already do that? I would guess go users are more interested in contributing to go. Plus the compiler people who are good at c and are already contributing can probably get up to speed with go quickly if they want to and don't know go yet. Or they already know go because they use it.
I think it is similar to what some people say that they will contribute to open source project only if it is on github. So it is not logical but nonetheless many want it.
