I don't understand the purpose of this restriction, considering that Google doesn't impose any limitation when translating web pages. It's worth pointing out that Google Translate's API has a similar limitation: "the maximum size of each text to be translated is 5000 characters, not including any HTML tags". Google's translation card from Google Search has a different limit: about 2800 characters.
