Unfortunately, they haven't. In Europe I get receipts with different
crossing-out patterns almost every week.
And, with "they" I mean the builders of point-of-sale terminals: I
don't think individual store owners are given a choice.
Though I believe I have noticed a good trend in that I get receipts
where *all but four* digits are crossed out more and more often
nowadays.

to security problems, at least not without a great deal of review.
You see, most vendors these days replace all but the last 4 digits of
the CC number on a receipt with X's. But it must be boring to do the
same as everyone else, so some bright person at one vendor(*) decided
they were going to do it differently: They X'd out *just the last
four
digits*. After all, who could guess the number from the 10,000
possibilities?
Ahem.

all I know they've long since fixed this.
