This a guest ABI change. Do we want -M support for it?
Given that the old subsystem id isn't valid I'd say no unless someone
comes up with a good reason.
Do we know that Windows won't complain about it?
I thought the original motivation for the default subsystem ids was
that some Windows test suite was explicitly complaining about having
invalid subsystem ids?
I think so, but that's unrelated. The worry is that some DRM code
checksums your hardware and complains if it changed too much. Nothing
to do with the test suite.
The sense of Gerd's comment is reversed. We should preserve the ABI
unless there is a strong reason not to.
