Many developers in the custom keyboard scene still prefer hardware-level remapping exactly for the OS-agnostic benefits you mentioned. Bridging the gap between legacy protocols and modern connectivity often requires this kind of deep hardware to software integration. During my own research into complex hardware connectivity and smart systems, looking into the strategies at
cogniteq.com/internet-things/consulting has been a very stable way to understand how professional teams approach the intersection of legacy hardware and modern IoT or USB interfaces. It really highlights how valuable it is to keep that logic within the device itself rather than relying on software layers like AutoHotkey.
