Given xip has been deprecated for a long time now, yet still is the format Xcode is distributed in, I highly doubt hidutil will ever disappear from macOS. Apple

Given xip has been deprecated for a long time now, yet still is the format Xcode is distributed in, I highly doubt hidutil will ever disappear from macOS. Apple just won’t really update it anymore, just like they haven’t changed xip (not like hidutil has seen any significant changes, but still)

Agreed. seatbelt/sandbox-exec has been “deprecated” for many, many years yet it still underlies all of the system’s sandboxing and Claude et al. use it for their own sandboxes. (And so do I — writing seatbelt rules is the only chance I get to write lisp-flavored anything these days.)

  This is only tangentially related, but libuv and mio's Windows implementations use the undocumented AFD readiness-based poll interface [1], since there isn't a documented readiness-based interface on Windows. The undocumented interface is now effectively stable since, among other reasons, Microsoft uses Tokio in some of its products.

    libuv does all sorts of shenanigans, like using the undocumented fields in STARTUPINFOW the CRT uses to pass file descriptors to processes inheriting handles so that you can open whatever file descriptor you need in your children processes like in POSIX But Microsoft kind of expects this crap and will support it until the end of time; Apple can't give a crap until and will readily break programs even when they use legal APIs

Similarly, launchctl has long-deprecated subcommands. I initially tried using the new subcommands, ran into issues, and told myself I should have known the “deprecated” ones were the way to go, now and forward.
