Very few commercial products are able to drop Windows 7 support (and like, literally zero enterprise products can drop Windows 7 support).
So, no matter how nice UWP gets, most companies that would still be willing to write a native Windows app are 5+ years out from being allowed to adopt it, entirely because of how Microsoft chose to release it.
Might not be an issue in 5 years, by then MS will probably has a new new framework .
You would be suicidial if you based any product you want to sell to business on UWP. Not only doesn't it Win 7 or 8 but I don't see in what way UWP is better than WPF.
UWP is great if you are exclusively deploying to brand new Windows 10 Embedded devices. (I think this is now called "Windows IoT Core" or something similar). That's what I've been using it for, and that's worked well. It carries a nice side benefit that our sales team all has Windows 10 Pro laptops, and UWP 'just works' there too for sales demos, presentations, and such.
But I agree, selling UWP apps to businesses for traditional desktop use is ridiculously difficult.

For a long time, UWP was the only way to get a working WebView (one based off of Edge instead of IE). But I think they fixed that and backported Edge to WPF a few months ago. (EDIT: they did kind of fix that - https://blogs.windows.com/msedgedev/2018/05/09/modern-webvie... )
This would be a great thing for us. But we already have a huge investment into WPF. How do we get this to UWP?
Now in face of this announcement, not sure.
Naturally this matters little to those enterprises doing plain CRUD applications with default L&F.
One big improvement in UWP is that Visual C++ finally merits the name Visual, although it still fails short of C++ Builder's RAD tooling.
And overall the sandbox model, however from the last Build it appears that Redstone will get an improved sandbox for Win32 apps as well, alongside MSIX support.
On one side it is a big reason why they have achieved their market size on the desktop, on the other side we reach this kind of situations where new tech improved tech like Singularity, Midori, Longhorn or now UWP gets thrown into the garbage can in the name of backwards compatibility. Quite sad.
