For now, the 'coefficients' argument default value of CovarEffect is (None,), which corresponds to 1 unknown parameter at instantiation when the model structure is still potentially unknown. As a concrete impact, for instance, the property .nb_params returns 1 in that situation, instead of None, or an error. This may have harmful consequences.
