Maybe but I'm not totally convinced it's enough. For small apps which are only currently on iOS this might be interesting, but for the large pool of applications which currently target web, iOS and Android, doing extra work to support a mac branch of the application is still that: extra.
Those users are already supported by your web application, and even if it's relatively less work than creating a separate native mac application, adding a mac branch of your iOS app will still add effort and complexity to implement and maintain. And that would be to serve what's probably a tiny minority of your active users.
What is Apple offers a touch screen? Then it becomes essentially an iPad with a keyboard..
Edit: imaging lifting your hand from the table and poking screen for several minutes. Screen wobbles each time. Your hand gets tired from being suspended, but putting it back is almost too much work. Apple might invent something, but there is only so much to be done with certain form factors.
You may want to try one in a store, I personally changed my mind on the 2-in-1 form factor after using one for a few minutes.
The main issue is that Windows 10 is quite bad at dealing with the transition between laptop and tablet mode, similar to when you connect an external display the screen blinks a few times, everything resize hysterically, so you have to wait a few seconds for the UI to transition.
Edit: the touch display is just way too practical when you want to quickly scroll a page or touch a button located on the opposite side of the screen. IMHO it doesn't have to be something you use all the time to be worth it.
I would use the mouse/pad/keyboard 90% or maybe 95% of the time — but the inability to just tap the button or pinch-zoom or whatever the other 5% of the time... it's just stupid.
All 5-year-olds perceive screens that you can't directly interact with to be broken... and they're right.

I saw someone attempt to play Slither while testing an iPad Pro with a mouse recently. It looked fairly awkward and unnatural.
I see it more as a stepping stone. It's difficult to imagine how a UI designed for iOS would ever not feel strange on a laptop. But SwiftUI seems like a great tool for sharing large amounts of code between platforms, with some branching to cater properly to each platform.
However given the current dominance of web interfaces for desktop software it's hard to imagine iOS apps becoming relevant on mac anytime soon aside from a few special cases.
