Taking into account the feedback from the SUSE packagers (about how dropping support for Qt 5.9 LTS the very month Qt 5.12 LTS comes out is a problem since not everyone can upgrade to Qt 5.12 LTS right away) I have modified the policy to temporarily support 4 versions when the oldest (and newest) are LTS.
