The readme says it is aiming for a “web look”, with no intention to make it look — and, presumably, behave — native. As a user, that’s not what I expect and hope for from a desktop application.

That’s not accurate, there are cross-platform toolkits that achieve at least a close-to-native look&feel. This is very different from giving up on it entirely and going web-style UI.
