I wonder if this will be one of the unintended (intended?) consequences? Normally the best way to get a pay increase is to apply for jobs that pay a lot more. Previously you could apply for a job that paid much more than your current role. Your new employer might assume that you were on something similar or a little bit less. Now employers will be able to see what you were paid previously and will probably not offer much of a pay increase, or you'll have to have a really good reason why you think your salary should be doubled.
