I think MDC is definitely less crunchy than years ago. I've only been on for 3.5 years or so, but I've noticed some dissatisfaction amongst more "crunchy" mamas.
AFM, I didn't know any better with my 1st pregnancy and just went with it when the OB (whom I'd never met before) automatically got out the trans-vag wand. It turned out to be a good thing, as it was an anembryonic preg, and we'd been getting ready to announce it at our wedding a week later.
2nd preg, I was freaked and HAD to have the 8-week scan. I hadn't found MDC yet, but I'd had a friend who lost a trisomy 16 baby, plus I was 36, so I had the quad screen/NT scan. Then the anatomy scan, then I developed pre-e, and I had weekly scans which I agreed to readily as they helped me keep baby in longer (I was with a CNM group, but OB started talking inductin at 35 weeks).
3rd preg, I wanted only the 20-week scan, as we planned to HB. Then I had spotting at 10w and asked for a scan. Found out embryo didn't develop past 7w3d. So now, with 4th preg, I NEEDED that viability scan (as others have said). Although I'm 41 this time, we skipped the NT. We had the 20-week scan to make sure baby was/is healthy enough to birth at home, which she is. At that scan I was diagnosed with partial previa. I'll have another scan at 32 weeks to make sure it's resolved - I really want that water birth!
