Suggestion to Rename `HttpRouter.del` to `HttpRouter.delete`

METHOD is an HTTP request method, in lowercase (e.g., get, post, put, del).

TBH I don't like the curve ball of having

HttpRouter.del

HttpRouter.del

instead of using the actual HTTP method in lowercase, which would be

HttpRouter.delete

HttpRouter.delete

I would even go as far as suggest to add

HttpRouter.delete

HttpRouter.delete

and make

HttpRouter.del

HttpRouter.del

an alias and eventually deprecate it over few major versions.
