Here's what I do know. If I look through my desktop computer platform, I find both the "Phone" and the "Message" apps. They just dont seem to be hooked up to hardware. Except I can send texts in a limited fashion from my desktop, with a limited popup window. So since my Desktop Windows 10 Pro has the frame work built into it, it seems likely that if they wanted it to happen, it is relatively easy for them to make it reality. It's really not that hard for them.
Oh yea and before I lost my massively fast broadband connection, I was actually able to have a texting windows with all my contact and text history available, not sure if that was just a part of the insiders program or not. So, yea its very likely.
