I kinda hate the new icon and I don't think any new icon should be taken without more people taking a look at it and sharing their two cents. I have the same problems with it or agree with the rest, to highlight a few.

* the new one is too wide and thin, doesn't quite fit into the overall square profile of the macOS icons

+1
 
* I don't think it needs the tilde

+1 - I think it should NOT have a tilde, that's a major change, and it's fine without it.

I think it just needs some tweaks to find a more middle ground with the vanilla and extended icon.

Extended and Vanilla are basically the same, right? And the extended one has a better quality, how about  just adapting from the extended icon with minor changes? This is very drastic, jumps to my eye, and it's not getting better with time.
