There is no argument having short and meaningful urls. Assume also the web application always generate the right urls without parameter order problems.

The difference of opinion is because if I get requests
example.com/?param1=1&param2=2
example.com/?param2=2&param1=1
in both cases I will return 200 OK. While you would return 301 redirect in one case. That's the difference. Although the web engine will always generate one version of the urls.

Yes and the urls I prefer to generate are 100% content related and without identifiers.
example.com/this-cool-widget
example.com/the-old-name
example.com/an-old-typo
..etc
