Shim for $.browser check

A shim has been added to the Aloha object to replace the deprecated jQuery.browser object. Aloha.browser now performs the same function as $.browser.  Code references to $.browser have been changed to Aloha.browser.  We are using this approach at Constant Contact to allow Aloha to be run in our applications using jQuery 1.9.\* and 2.\*.\*.  

Not sure how this fits with your vision for browser detection going forward, but though it would be useful to submit.
