@selmaVH1 what do you think about adding the other comments in the issue report. While not specifically in the code, it helps understand why and when to use it, hence probably helpful for many users. I'm referring to
It avoids the need to use the same expression multiple times throughout a model if the same result needs to be used more than once, and also permits use cases which otherwise are not possible (e.g. generating a timestamp value once and then reusing this throughout a model -- if every use recalculated the timestamp then the values would differ during the model's runtime)

I think there is a switch here (https://github.com/qgis/QGIS/pull/54358/files#diff-dc398bcb04bd91d852555624aeccefce91fe509dc7ad879ba12ce978d67fa238R82)
