As Windows starts on-boarding their unified Electron model (I can't recall what they have named this), I suspect we'll see more lightweight Electron desktop apps. But for the record, I like purpose built, old-fashioned desktop applications. I prefer traditional desktop applications because:
* Traditional applications economize on display real-estate in ways that modern web apps rarely do. The traditional desktop application uses compact controls, very modest spacing, and high information density. While I have multiple monitors, I don't like the idea of wasting an entire monitor for one application at a time.
* Standard user interface elements. Although sadly falling out of favor, many desktop applications retain traditional proven high-productivity user interface elements such as drop-down menus, context menus, hotkeys, and other shortcuts.
* Depth of configuration. Traditional desktop apps tended to avoid the whittling of functionality and customization found in mobile and web apps. Many can be customized extensively to adapt to the tastes and needs of the user.
Bottom-line: Yes, for some users and use-cases, it still makes sense to make desktop apps. It may be a "long-tail" target at this point, but there's still a market.
