In this case we already have a reference. Lastpass had a native mac client. It wasn’t great but it was fast and relatively light weight. Their new Electron version is borderline useless for enterprise use. It takes minutes to log in, it’s slow and the interface it flaky.
It’s not unrealistic that people will fear the same is going to happen to 1Password.
VS Code is the example that shows that you can create great Electron apps, but can you name three more?
Electron get a lot of flak, because it’s misused by webdevelopers, who thinks it will magically make them able to write good desktop app.
Microsoft also had the good fortune that few expect an IDE to be particular light weight. For what it does no one is going to care if it eats a gig or two of RAM. If my chat client or password manager does the same I’m going to be annoyed.
