What should I think about it? You need a better question.
If you are asking could you use a local regulator on each module I would say yes, but measuring the current in a better way will work better and be cheaper in the long run.
Better because you are eliminating a source of error in your calculation.
Cheaper because you are eliminating parts requiring a heat sink, being either the Rsense resistor or the local regulator package.
