There aren't many cases where uses got their Bitcoin back after send it to wrong address or set extremely high fees, so i doubt it.
I don't think it's common nowadays because probably people are more careful and there are often warnings if the fee is set too high, but at least with high fees I remember people even getting a lot of their money back from transactions mined by P2Pool, as unlikely as that sounds.
While it's true that people are more careful and wallet is "smarter" these days, you missed my point.
AFAIK there are very few cases when user send Bitcoin to wrong address or spend too much on fees and got their Bitcoin refunded.
