I can't wait to get rid of some of my Electron apps in favor of proper native ones. That feature alone would be worth the upgrade in my opinion.
But that's not to say I agree with how they've implemented the permissions dialogs. As a developer who had to deal with them I found several glaring bugs in Mojave, not to mention a sub-par UX. I'm sad if they haven't improved on that.
Upgraded to Catalina without a second thought after seeing that Podcasts was included.
It's tiny, but it's things like that that make this feature cool. Just a little less friction between the platforms.
That was launched alongside macOS Sierra.
