Is it ok to add properties to WordPress userSetting object directly?

WordPress has a utils.js file which has provided four utility functions to manipulate settings and store them in a cookie. it also creates a global variable called userSettings with the following properties:

• url


• uid


• time


• secure

Now, my plugin also wants to create one/more properties and instead of creating a new object I thought I'd use the one WP has already created.

Is it a good idea to store my plugin settings in this object. one of the properties is the full url of the website.
