> I'm well aware that Electron has a large RAM footprint and installation size, but doing a polyglot architecture instead puts more cognitive load on you. Projects that mix multiple languages are a pain just to manage.

I'm not directing this at you, but to all developers using Electron and its ilk:

Show some empathy for your users and shoulder that cognitive load so that your users can have their hardware back. That's just courtesy, and a responsibility a good engineer takes on. There are so many more users than there are of you, their aggregate gain from your efficient software far outweighs whatever extra work is necessary to do the decent thing.
