I'm a developer who has built and published several apps. I want the biggest possible audience for those apps. Why would I limit those apps to Windows? (Or even to any single platform/OS?)
Web apps work everywhere. The web has grown increasingly powerful and capable. Why would I invest in a technology that can only run on a single OS? Doesn't make sense.
Just build for the web. You can package web apps for all the major app stores using PWABuilder[0], no Electron needed. Just fast, lightweight apps distributed by app stores and accessible from the web.
