Most web application servers have already equipped to be able to easily parse parameters out of the URL path for many years, of course, it's definitely nothing new, it's just that historically, people reached for URL query parameters for this sort of thing. After all, making a request with query parameters is basically built into the browser; you can do it with <form> and anchor links with no JS needed.

Presumably, because of that, many pages will continue to use query parameters for the foreseeable future. I think that's fine, but at least for APIs, the QUERY method could eventually be a very nice thing to have.
