> Each ticket is one commit. If you revert one commit, you are guaranteed to have a working piece of software and you won't have a potentially not even compiling intermediate commit that was subsequently fixed up during a PR, which can happen without squashing.

This is the key point and I liked it so much that I bookmarked it. Hope you don’t mind. :)

I frequently have to debate with my teammates on the value of squash merging into our mainline branches. Another value add that squash merge brings is that it enables what I call “accidental documentation”. You get a easy to parse log of work that was done and a link right to the PR with a description and any discussion around it. As a lead I frequently need to coordinate teammates and communicate technical decisions. It’s invaluable to be able to just pull up the commit log and go right to the work in question without having to wade through a bunch of noise.

It also helps a ton with writing release notes.
