Testing with Python 3.4 has been failing on AppVeyor for quite some time. Fixing it is probably not worth the time and effort (and perhaps quite hard, if the problem is the really old version of pip AppVeyor has bundled with Python 3.4), so I am proposing that we drop it entirely. On the other hand, adding Python 3.7 and 3.8 to the list would be useful.
Also, the fact that we're not building Python 3.4 wheels from CI might be of interest here. :-)
