For comparison, the entire JVM for Desktop, including Swing, AWT, Themes, JavaFX, the entire stdlib, three separate optimizing JITs, profilers, graphical tracers, etc, combined, is below 64MB.
The entire Android OS, every part of it, including all toolings required to build apps, is still below 200MiB. This includes libraries, default apps, UI, compilers, tools, stdlib, firmware, etc.
My point is that if Electron was provided by default just like .NET or one of the apple frameworks you would not mind it that much and you will think apps built with it are lean when in fact to create a UI rich standalone executable you will require a lot of things to get up and running.
