One of Electron's main selling points is that you control the browser version. Anything that relies on the system web view (like Tauri and Wails) will either force you to aggressively drop support for out-of-date OS versions, or constantly check caniuse.com and ship polyfills like you're writing a normal web app. It also forces you to test CSS that touches form controls or window chrome on every supported major version of every browser, which is just a huge pain. And you'll inevitably run into bugs with the native -> web glue that you wouldn't hit with Electron.
It is absolutely wasteful to ship a copy of Chrome with every desktop app, but Tauri/Wails don't seem like viable alternatives at the moment. As far as I can tell, there aren't really any popular commercial apps using them, so I imagine others have come to the same conclusion.
But sure, you could have some specific need, but I find it hard to believe for these simple apps.
This is a new era where “if it works more or less well, ux/dx is fine, let’s ship it” has more moat than ever. Everything else is really secondary.
