Does it though? iTerm2 is the most feature-rich terminal I've ever used, and even then it's several orders of magnitude smaller then Electron (cloc says it's around 111K lines of Objective-C, with around 38K more lines split across Python and C++).
That's just not true.
Most open-source people want to be able to read, audit, fix, and (if it comes to it) maintain other people's code. 14+ million lines of code make this virtually impossible. (To be fair: Electron-based apps aren't the best example for the point I'm trying to make.)
Rate of change is another very useful metric.
I personally hate the load times. Node apps always seem to need to think for a second or too. Sublime Text v VSCode is pretty bad. Sublime Text v Atom is even worse.
When you're moving fast and in your flow, it gets to be really annoying.
