That's less of why the app couldn't be written in Electron and more of why Mac users wouldn't like an Electron app.

Perfectly valid reason why someone would want to write their app as a native app though, and I appreciate that.

Some of those are definitely things Electron gets wrong and should correct. Handling system-wide accent colors is exactly the kind of thing my UI kit (Electron in this argument) should be handling and not forcing everyone to re-invent.

I've never used or even heard of the titlebar file handling functionality and had to search that right now. This is exactly the kind of thing I've said about discoverability. I used OSX for three years daily, and I've been using it on and off as needed since around 2010. Some things that people love and use all the time are just not obvious to everyone.
