build_model_size_report not include variables in objective function

[ZedongPeng]

In the build_model_size_report function, the activated_vars only includes the variables in activated_constraints and activated_disjuncts.
Should the variables in the objective function also be included in activated_vars? Although all variables included in all_vars.

The models that have no constraint motivated me to ask this question.

In the cvxnonsep_psig30.py example, there is no constraint. When I use build_model_size_report(model), the output is like the following:

activated:
    binary_variables: 0
    constraints: 0
    continuous_variables: 0
    disjunctions: 0
    disjuncts: 0
    integer_variables: 0
    nonlinear_constraints: 0
    variables: 0
overall:
    binary_variables: 0
    constraints: 0
    continuous_variables: 15
    disjunctions: 0
    disjuncts: 0
    integer_variables: 15
    nonlinear_constraints: 0
    variables: 30
warning:
    unassociated_disjuncts: 0

I can use the information in overall, but I am wondering should the activated_vars also includes the variables in the objective function.

Btw, the information of the objective function is not collected here. Should this also be included?
