Yeah for a small tertiary apps then Electron is a huge performance burden to put on your users. They might just choose it's not worth it and not use your app.
On the contrary if it's a large app that the user spends lots of time in, then the performance overhead might well be worth it for the user.
Imagine in the first case that it requires a base load of 10 units of energy to run and gives 2 units of output, while in the second it still costs 10 units of base load energy, but now it gives 100 units of output. The base load becomes relatively irrelevant.
