A bit more heavyweight, but we implemented a rotation program when I was managing an internal tools team at a previous company. We'd trade an engineer from our team with an engineer from a feature team for a quarter.

The amount of improvements to our collective understandings was super valuable. Feature devs got to help fix problems with their tools more directly (while also learning that it's not always as straightforward as it may seem), and we brought back much stronger insights into the experience of actually using our tools day-to-day.
