EA211 has an aluminum block, though, and oil pan 4 was talking about mixed material engines using these strategies being a bad idea. Valid for EA888 Gen 3, though, that is a mixed material engine. (Also, by US standards, EA888 Gen 2.5 (we don't get the true Gen 3, IIRC) has been considered unreliable (then again, basically every recent VW engine other than the EA113 2.0 8v is unreliable by US standards), although not for that reason.)
Back towards the topic, though, it looks like Toyota is switching from the 1NR-FE, to the 2NR-FKE for the European-market Yaris:

Larger displacement, more power and torque everywhere, but they also went to the wide authority VVT version, which enables Atkinson cycle operation for higher efficiency, and they're doing this due to more accurate European fuel economy test cycles, to improve real-world efficiency.
