If Electron means that people actually make cross platform apps, I'm all for it. Slightly suboptimal apps are better than no apps or discontinued apps.
Well, then this seems more of a packaging problem than an actual tech problem.
In an ideal world that would be the next step if the app reaches a large audience. I'm not sure that from the upstream developer's point of view the investment of limited resources into per-OS packaging is a good idea at this stage...
And not in a way for engineers that want to host applications, or people who care about single threaded web-frame apps chewing up their laptops battery and RAM.
