No no no there is huge misunderstanding here, this has nothing to do with flirting with either internal or external annular rings. I can achieve this goal with annular rings of 1000 mils and never see break out on my 12 mil hole. It would give me the other 988 mils back on layers not connected only. My suggested feature has nothing to do with modifying the padstack. the more I think about it It is a DRC issue. . One might gain as much as a few mils of routing space. > You are correct but on many occasions all I needed was a few mils.
