I am getting the same feeling, as Microsoft's track record with such things hasn't been stellar, anyway. A crucial point, however, is that Windows Server only has had a kernel new enough to support this for a little while (not counting previews and RCs for obvious reasons), which I'd say is the one Microsoft platform that would benefit the most from this. Also, since it's really hard for outsiders to find documentation on Windows kernel interna (which means as a normal user you'd be tracing syscalls at best), I suspect a key motivation was to improve observability for the Windows dev team, so we possibly also wouldn't be able to estimate of how much use the port really is.
