I do prefer the piped version mainly because it removes annoying nesting but that's not high on my prioritized list of discomforts. The issue of deeply nested function calls is a thing, but I just use some temp variables to avoid it when it really starts looking ugly.

Then again, this is my typical opinion to a lot of the proposals - I see what this is useful for but I haven't experienced enough pain to really argue for it. However, if it does make it into the spec then I will use it probably because it's there.

I also recognize my stance as one that not many people like in other contexts because it can be interpreted as me not looking to improve my situation. But on the flip side I think cluttering the language specification with a lot of superficial syntactic sugar is a mistake.
