I know. But they are not reliable. If you disable IE6 and IE8 permutation 
the bootstrap file still assigns a valid ie6, ie8 value to the user.agent 
property because the user.agent detection code does still contain the 
ie6/ie8 checks. onPropertyErrorFn will only be called if the user.agent 
value contains an invalid value. So to make it work way better the 
detection code should be aware of the enabled/disabled permutations and 
only do the required checks instead of all checks. That way the 
onPropertyErrorFn function would become useful for this scenario.
