It's not going to matter, most Electron apps look out of place on the Mac already. The developers are not going to care and probably most users are not going to care either (I used to be staunchly against Electron for this reason, but gave up, and now I choose just enjoy apps looking the same between platforms).

Apple neglected the desktop from ~2016-2020 and made two frameworks that are unpopular among developers (Catalyst and SwiftUI) after that. Outside some indie devs, the native Mac app ship has sailed. Even developers that had their roots in macOS (e.g. AgileBits) have given up and switched to Electron.
