Pure js inline generated links simply fail to be detected with a lot of the common HTML parsing tools they might use like mechanize or hpricot.
Sounds deliciously evil.
I myself use Honem's method for updating and determining when an update is needed. I like the "If it isn't broken and/or blowing chunks all over your UI don't update it", statement as that is my update determining method. I used to be a WAU user back in the day, however I weaned myself off it. Besides with the ending of Threat 1.0/2.0 (replaced by the built in Threat), there is no need to update "just before you log in".
