ASIO was just one of the first audio APIs to provide high-quality, low-latency audio. Many people haven't realized that native audio APIs have moved on since then. macOS has proper audio APIs out of the box, and arguably since the introduction of WASAPI exclusive mode and WaveRT in Windows Vista, Windows has all the needed tools as well. But most of the more "professional" DAW products (in particular those by Steinberg, the author of ASIO) seem to ignore the existence of those. REAPER is one of the exceptions. Even WASAPI shared mode latency is really usable (below 30ms), but not low enough for tightly synchronized real-time recording. Linux audio can be set up to provide low-latency audio as well, but I cannot comment on the details there as I'm not using it for that purpose.
