The benefit of Accept Culture change

Maybe the first question should be: what is the impact of the "Accept Culture change"? Does it only change country culture or culture of ALL provinces?

If that only change main culture… what is the benefit of Accept Culture change at all?

Accept Cultural Shift is a good decision to take if you are a small nation that is expanding into a different culture group than your own, because you can move the capital, accept a cultural shift, and then you no longer suffer from the penalties to tax and manpower and rebellion from being a different culture. The decision changes the culture of your nation's government, not the culture of any particular province.

For example if you are playing as a greek OPM and expanding primarily into italy, you can change culture to italian. This means you don't have to spend time and points on converting all the italian provinces to greek. Instead you just convert your original province to italian.
