Out of curiosity, when was the last time you looked at DataFrames.jl? A huge amount has happened in the last year. Plus, if you want more tidy-like syntax, you can go with Query.jl, (or DataFramesMeta.jl, though that isn't quite finished updating to the the new DataFrames syntax), or of you just want pipes on DataFrame operations, there's Pipe.jl and Chain.jl.
I don't think your comments are harsh, you need what you need and you like what you like. I do mostly data wrangling too, but feel much less constrained with Julia than with tidyr. Sometimes having constraints and one right way to do things is good, but it's not for me.
Also worth noting it's not necessarily on the language developers to do this. Even in R, tidyverse is in packages, not in the base language.
