I did the switch to the binary host yesterday and seems it went well. I followed the instructions in the quickstart [1] and issued an emerge -p --empty-tree @world to see what would happen. Many packages were shown to be installed from binaries, while others couldn't be installed from binaries because of the USE flags. In those cases, emerge listed which flags I should change to use binaries: some of these changes were acceptable to me, while others weren't. At the end, I reached the point where more than half the packages could be installed from binaries: moreover, these included the largest ones, like qtwebengine and libreoffice, while many of those which couldn't be installed from binaries were perl, python or ruby packages which usually take a very little time to install from source. In particular, most of Qt and KDE packages could be installed from binaries (the number could have been greater if I had accepted to change a few more USE flags). I didn't install all of those packages, but I tried manually emerging a few of them and they worked correctly, so I can say I'm very happy with the result and of how easy it was to enable this feature.
