IMO we shouldn't worry about ABI on Windows. And not because "meh Windows", but since Microsoft breaks C++ ABI with every compiler release, which is quite frequently these days. In general C++ ABI stability just isn't a thing on Windows. And we are both the upstream and the downstream for the releases anyways. To that latter point, I guess really it matters what the KDE Windows team thinks. Ian
