If you want to use the visa legally, you need ongoing activity, some people think requirements stop after they got the visa, but that is stated nowhere, so there is no reason to believe that is true.
Chances getting stopped when you reenter the country are very low, but there is a risk.
What will happen in the future nobody knows, but if they want they can implement all kind of checks to see if you comply with the visa requirements.
