Why is there no Regex Delim option in CSV.jl?

I regularly ask myself why this is not implemented.
CSV.read(filepath, DataFrame; delim="\s+")
i know that this works.
CSV.read(filepath, DataFrame; delim=" ",stripwhitespace=true,ignorerepeated=true)
and yes, it is not the same…

So I guess the answer is “because no one has implemented it”.
