When will Windows 10 include native support for Auracast streaming? (opens in new tab)

My Galaxy S25/S26 Ultra supports Auracast, letting me stream Netflix to two Galaxy Buds4 Pro at once. Why isn’t native Auracast broadcast available on Windows 11? Insider builds have a limited Share Audio feature for select devices, but I want full native Auracast support for all Windows 10 laptops/tablets.
