Yes and I suspect that this is why it was never added to AWK. I,and I am sure most people, have an AWK filter to transform their csv or whatever format to a format that AWK can use with an appropriate FS and RS. Their "but why" section should really go into more detail about why filters are not 100% if your data has the possibility of containing your preferred line/record separator. But real world, I have never had a situation where a csv-to-awk filter (written in awk of course) did not work.
