That said, I'm against including code of this nature, when we don't have adequate testing or CI coverage. It's a recipe for future regressions if the XP codepaths are not tested. It's difficult for a volunteer-driven project to adequately support and maintain dead platforms. There is a cost to adding and maintaining this support, which needs to be borne in mind. As is the quality of the support if it's not being actively and routinely tested. While I am willing to test, use and support libtiff on a wide range of contemporary platforms, Windows XP is not such a platform.

I agree. XP is a dead platform. People still using it are unlikely to upgrade their software versions anyway. Or if they want to, they can maintain their own fork. Such patch has no value for the upstream project (and I strongly suspect the root cause for the issue is not really understood. Not being able to read more than 64 KB at once is super dubious even on XP)
