Does MTK nominal metadata for variables set abstol when solving ODE

when you define a variables

@variables begin
x(t), [nominal=1e6]
y(t), [nominal=1e-3]
end

will it essentially do the equivalent of setting abstol to a vector of absolute tolerances rather than a scalar, by multiplying the abstol you pass in

sol = solve(prob, u0, (0,100); abstol=1e-6)

by the nominal value? Or is it ignored ? The Documentation mentions it being used for optimal control problems but not for plain old ODEs, just want to clarify

well, it seems like it possibly has no effect?

doing this:

integrator = init(prob, solver)
integrator.opts.abstol

just returns the default abstol of 1e-6. So it would seem that setting nominal is no help for setting tolerances, at least AFAICT.
