rest_alias property is very limiting - can't use DELETE/PUT

[calvinalkan]

It's not possible to create a rest alias for routes that use DELETE/PUT/PATCH.

For example, this rest_alias: 'rest_alias' => '/wp/v2/posts/(?P<id>[\d]+)',

Will always get matched to the "update route".

But the delete route for a post uses the same route pattern. But with a different method.

I think a feature needs an optional method property, that's also exposed in the rest api under /features

Relevant code parts below:

	/**
	 * Gets the REST method for the feature based on the feature type.
	 *
	 * @since 0.1.0
	 * @return string The REST method.
	 */
	public function get_rest_method() {
                // This would be new.
                if(this->method !== null) {
                   return $this->method;
                }

		if ( self::TYPE_TOOL === $this->type ) {
			return WP_REST_Server::CREATABLE;
		}

		return WP_REST_Server::READABLE;
	}

$method = $this->get_rest_method();

		foreach ( $routes[ $feature_route ] as $route_handler ) {
			$methods = array_keys( $route_handler['methods'] );
			if ( in_array( $method, $methods, true ) ) {
				return $route_handler;
			}
		}
