Should we set the default value of `symmetry` to 1?

[maki49]

Symmetry analysis can reduce the number of k-points to speed up the calculation.

If calculation=md , the default value of symmetry is 0.
But if calculation=relax there's no such enforcement, should we set it to 0 like md?

maybe in MD cases, we should not take advantage of symmetry. And in practice, we often set symmetry=0 in the relaxation process of surface catalysts.
