How often do browsers break backwards compatibility? I don't think I can recall a single time I've had working code break due to a browser upgrade, with the exception of non-standard features (which is maybe what you're referring to, but then it's a known risk and you should already be aware of it). Edit: And if a client really does need version X of Chrome, you could give them the ability to pay extra to pin the version indefinitely.
