It shows you can write native cross-platform apps that are fast and have low system resource usage instead of the now default, packaging your app in a standalone resource-intensive web browser, aka Electron.
It's a shame we have a handful of people who can do this as a hobby project yet multi billion dollar companies with the money and manpower to do this don't, they chose Electron.
I get that this is early days for this project, but the issues are general for all of these non-browser, non-native UI toolkits. Hopefully we get there though.
Obviously screen readers are an important step, but we hope to be working with AccessKit.
In any case, though I'm not trying to represent Druid as ready for production use, I love seeing stuff like this. I think it's a good sign of what's possible and where things are headed.
Picard is a good example of a PyQt app: https://picard.musicbrainz.org/
I suspect the real reason is that web developers are seen as a dime a dozen and GUI programmers more specialist and hard to find. This was the main reason my team chose to do an Electron app. We were already doing React on the website and nobody had any experience with Qt.
This is a purposeful decision though. How else could they track a thousand different metrics about you without 20mb of Javascript?
1. Electron apps also have access to "your whole (userspace) system".
2. Electron has npm, which makes it ridiculously easy to add analytics code to your app. See, for example: https://www.npmjs.com/package/electron-analytics
