Once again, checkride failures has been a pretty common interview question for quite some time. It does have (possibly) more ramifications post-Colgan 3407, but whether there's a database to track such things or not is irrelevant. Applicants should be truthful and forthcoming with such information, and if they are not and outed I'm pretty certain they are pulled out of class and canned.
To say there will be more stress in check rides now than before, just because they will tracked, is a bit of a reach I think. The stakes are the same. The game may have changed, with the media of today, but unless you have been lying on applications, nothing will change out of this.
