adjustUnits issue colliding with Ignore option in Model

[phantomas1234]

model = ExampleData[{"Toolbox", "Glycolysis"}];
adjustUnits[{k["vh"] -> 1}, model] (*-> Millimole Hour^-1 Liter^-1*)

vs.

adjustUnits[{k["vh"] -> 1}, {r["vh", {m["h", "c"]}, {}, {1}, True]}] (*-> Hour^-1*)

the Ignore option allows on to exclude certain species from the generated mass-action rate-laws. They're not excluded though if they are the only species in a reaction. adjustUnits is not aware of that.
