Individual application maintainers are free to require new compilers. If you want to make 2015 a requirement for Kate, I think that's fine. It may need some CMake changes to check the compiler so that it fails early instead of failing inside a QStringLiteral halfway in compilation.

We could also agree on using MSVC2015 for all binaries KDE Windows releases even when it's not required by that particular app.

However, remember KF5 is used by third-party developers who may use older versions of MSVC. We must keep doing whatever ugliness is necessary (like QStringLiteral fixes) to keep all *frameworks* building in MSVC 2012.
