Not changed mine :-)
But my sister, who has had offspring, did. Means a less usual surname has hit a dead end :-(
I think someone has to do something to determine what to call the kids. It's easier to understand if it is always the same gender, and traditionally that is the woman. It doesn't really change who one is, merely what one's label is. The rest is all in the individual's mind.
And it makes genealogy, tracing the female line back, more interesting :-)
