I *totally* agree that it's important to control diabetes in pregnancy, if one has it. And I even am fully supportive of discovering pre-existing undiagnosed diabetes in women who are pregnant.
BUT, the beef comes with testing all pregnant women and the old protocols and unfounded testing limits, etc., that are used in this test. Here's a link to background info on the GD test:

I also tend to be hypoglycemic so there's very little reason for me to do this test. My MW did do a finger prick after a meal at one visit during my last pregnancy. Apparently all was normal and that was that! I expect the same this time.
But, yes, it's very important to control things like diabetes, especially in pregnancy. In fact, baby's reaction to sugar is one reason that everyone should watch sugar intake, especially in late pregnancy. Not only does it make bigger babies, but baby's blood sugar will drop significantly after birth if mom's had lots of sugar and then baby is suddenly on its own. Not fun!
(Yes, this is why I'm eating my Cinnabon NOW and not in 12 or 16 weeks!
