Is that why they are doing this? Did your little chat bit tell you anything about Mojang's stated rationale, which is what I asked about?

Also, GLFW reports both the scan code and the key code, just like SDL, so I'm not sure I really trust those technical details either. Usually, you want to use scan code for some things (e.g key binds) and key code for others (e.g typing), so you can't have a global switch.
