Well in its original form Roe laid out, without any legislative input, a full on trimester system in which abortion was definitely legal until the third trimester, thus making regulations like the ones you mention impossible. This was somewhat relaxed with PP v Casey, but I don't think the kinds of regulations you mention would even be legal then. Thus, by making the compromise position untenable, it naturally brought out extremists on both ends.
