I did a bit more reading and noticed in the WebAIM stats that Narrator usage is indeed on the rise. Given that it is included in the OS, I would hope that it ends up as the defacto standard in much the same way as VoiceOver is for macOS.
Really interesting to hear some of the technical details from someone that worked on it - thank you!
