Don't know how large a presence Trek has in Europe, but many of their competitors there use aluminum forks for their touring bikes and have done so for many years.
Edit: just looked up Koga-Miyata's (well-respected) touring and trekking bikes. For those bikes, their search filter lists five fork types, including variants of carbon and aluminum, with or without suspension. None are steel.
