Good idea :)

“Rather than using $.browser to detect the current user agent and alter the page presentation based on which browser is running, it is a good practice to perform feature detection. This means that prior to executing code which relies on a browser feature, we test to ensure that the feature works properly.

To make this process simpler, jQuery performs many such tests and makes the results available to us as properties of the jQuery.support object. The values of all the support properties are determined using feature detection (and do not use any form of browser sniffing).”
