There doesn't seem to be huge disagreements of that so if no one really really complains in the next two weeks i'd like to declare as supported platforms what we have in CI which would be:
 * gitlab
   - debian (unstable)
   - ubuntu (xenial would replace trusty)
   - mingw64 (via fedora)
   - android (via kdeorg/android-sdk docker)

 * cirrus (in my github clone)
   - freebsd-11-2

 * travis (in my github clone)
   - osx xcode9.3 and xcode8.3

 * appveyor (in my github clone)
   - mingw64 (via windows itself)
   - msvc2017

Cheers,
  Albert
