I agree, but in the GCP world, a lot of these things are merging. My understanding is that Cloud Run, Cloud Run Functions (previously known as Cloud Functions Gen2) and even App Engine Flexible all run in the same underlying cloud run infrastructure, so it's essentially just some interface differences that to me now seem more like historical legacy/backwards compatibility reasons than meaningful functionality differences (e.g. Functions can now handle multiple concurrent requests).
