Before switching python_targets for the first time, you could use your news system to inform Gentoo users that 1) you are switching python_targets 2) it may be "a bit premature", and so, those who really want to have a stable Gentoo system should 1) do such and such changes to their config files and 2) wait about 3 months untill all the dust will settle. By the way, last time I have tried to set PYTHON_SINGLE_TARGET="python3_5" PYTHON_TARGETS="python2_7 python3_5" in my /etc/portage/make.conf and I got a vary strange errors from emerge afterwards: every time the # emerge --update --deep --with-bdeps=y --newuse --backtrack=120 --ask world command was run, a *new* package complained about something and system update aborted. I guess from that that the syntax of setting python_targets has been changed lately (may be, it should now be set only in package.use) but nobody informed Gentoo users about it. P.S. The said above together with the recent Gentoo signing key issue and sometimes "corrupted" daily portage snapshots that I download by emerge-webrsync make me think that even so called "stable" Gentoo lacks quality control and cannot be considered as stable and suted for those that really need a stable system.
