Yes, stylistic, or even "cultural".

IMO, this is a time when the one liner is more clear.  But if you start
trying to stretch that to extremes, it becomes worse instead of better.

That's fine.  That's appropriate.   But I imagine any of these can be done
with the intention of being more clever than clear.

BTW, what's pipelining style?  Like bash?
