Yup, it's a well established truism at this point that if you need a stable system (or don't have excellent data backups) you should never install the .0 version of any Apple OS. And while many Cocoa apps should be forwards-compatible out of the box, if you rely on Homebrew it may be several months before the packages you need are all updated.
Obviously just 1 data point, but I've been on High Sierra since the GM candidate came out. Smooth transition - everything just worked. Nothing about my development setup had to change.
