Accepting command line options does not make something Unix-y, IMHO. I assumed it was called a "Unix tool" because it reads data from a file/stdin, does something, then writes to stdout. If I needed to do something with JS as part of a series of Unix commands this would fit in the pipeline nicely. e.g. let's say someone wanted to do a one-off data transformation and they understand JS a lot better than Awk.
