If you want to have a higher probability that you can receive binaries from us, instead of having to build from source, don't upgrade yet. Same goes for High Sierra-specific build failures of specific ports that we haven't fixed or even discovered yet. If you want a higher probability that we find and fix those problems, wait.

In which order is the High Sierra buildbot building the binaries? How long does it take for all ports to build, in case it's set to do so?
