It is not really nitpicking when most Electron apps use tens to hundreds of megabytes of memory. If all the utility apps that I use regularly switched to electron, I would need an order of magnitude more RAM.

Moreover, these applications are then completely 'unnative' in the sense that the widgets do not look native on my OS, the widget behaviour is not native to my OS, the usual keyboard shortcuts are broken, etc.

Electron apps are the Java Swing applications of this decennium.
