To recap and conclude: both formats end up generating more work for developers, not less, provide little benefits to the users - but very tangible drawbacks - and can't even honor the promise of a single package that can be shipped anywhere.
I could go on for longer, mention how you're better of with something like Electron anyway if you're also shipping on other platforms but this thread is long enough... and I need to fix a Snap-specific bug. End of r̶a̶n̶t̶ thread 14/14
