It always astounds me when (inexperienced) developers play down build times as if they simply aren't that big an issue. They are hellish, creativity crushing monsters.

Also, static binaries -- so the DevOps guys don't hit you with sticks.

I still remember the first go program README.md I shipped. "Umm, get foo to box, ./foo in a way so that it runs persistently and at startup."

Easy way to get your apps to the front of the line in the deploy queue -- all the time.
