Thinking back after our discussion, this solution is not working :(
If you have two solvers: solver1 with param a and solver2 with no param, and a dataset with param a, you will end up with 3 columns for param a, depending on the combination.

I think the best course of action is to use prefix all the time. It is a little bit ugly but it is robust and don't require too much dev compared to introspecting everything.
