To these days, there are kids dressed at chimney sweep in a lot of weddings in many german speaking countries. I know one of my daughter did dress that way in a friend's wedding when I was living in Switzerland.

People think about the tradition of them bringing good omen and how cute they look, not gruesome children labor.

Haven't heard of children doing it, but similarly in the UK many working modern sweeps also do (paid) wedding appearances, kiss the bride for luck etc. Bit of a weird tradition! No idea how common it is, denominated by #weddings, not that, I'd guess.
