Why is the toolbar only on the mobile app? Would it take much more work to make it available on desktop?

I’m not trying to get a toolbar on the desktop, I know there are plugins to do that. I’m wondering, if the Obsidian devs created an official toolbar for mobile, why wouldn’t it be available on desktop? Doesn’t Obsidian have one codebase with Electron and Capacitor? I would assume that it wouldn’t take too much work to have the toolbar working on desktop.
