trailing slash in the url /wp-json

[superpoincare]

The url with wp-json doesn't redirect one to another.

Won't it be better if there's a unique url, with one with/without trailing slash permanent.

For example:

https://www.example.com/wp-json and
https://www.example.com/wp-json/

are different addresses whereas one should redirect to the other (?).

While I like the idea, there might be issues with backward compatibility.
For example, curl does not follow redirects by default, so a redirect would not work unless curl is explicitly told to follow redirects.
