We would like to be able to check that support_old_CalcTmunu_mechanism is activated in order to ensure that we will be able to read the stress energy. However, the parameters in TmunuBase are all default scope, which is private. The attached patch fixed only the parameter we required. As other thorns may want to check other parameters, it might be sensible to change them all to restricted.
