I don't read the parent comment as saying that vscode shouldn't be written in electron. I read it as the opposite, that they are defending the terminal emulator using electron.
Also, out of interest, what reasons would you give for vscode being written with electron?
I read it as sarcasm, cause writing a terminal emulator in electron is really a stretch, could be wrong ofc.
At first I was a bit irritated that vscode is build on electron. Then I found code-server, essentially vscode in the browser and fell in love with it. I can run a fully fledged IDE on a PI without using too much ram or CPU power because the client does a lot of the ui heavy lifting.
Then also the other way around, I use code-server on my powerful tower pc and can connect to it via vpn to run heavy coding tasks directly on the server while not miss8ng a single IDE feature. I use the metals plug-in to code Scala backend services and it works incredibly well. Much better then using remote desktop applications (nomachine, vnc, xrdp etc.) on the go. It's even better then ssh when the connection is bad, like mosh but for ui.
