> But Microsoft never added SCTP to Windows

Windows already has an in-kernel QUIC implementation (msquic.sys), used for SMB/CIFS and in-kernel HTTP. I don’t think it is accessible from user-space - I believe user-space code uses a separate copy of the same QUIC stack that runs in user-space (msquic.dll), but there is no reason in-principle why Microsoft couldn’t expose the kernel-mode implementation to user space
