Here's my take on Electron and anything else resource-intensive: if your UI is either short-lived (like a configuration window) or the main thing you're using (like an IDE), I don't really care how much RAM or anything else it uses.

A firewall configuration windows falls in the first category - you only open it very occasionally and for not very long, so it doesn't really matter how heavy it is. Where Electron (or similar) is really bad are things like Discord, Slack, Spotify, Teams, etc. where you'll likely be running many of them all the time, while you're doing other things that need those resources.
