I wondered the same. The main downside is that you need to do some processing to extract the entries from the dump and get the plain text of the fields you want.
I'm also a little surprised they didn't think Wiktionary was sufficient for languages apart from English. I could be wrong, but my impression is that it's pretty good for major languages[1].
