Yes, I could do this but what happens if then I upload a new style? I should manually add the template. And if I want to change the text for a typo? Uninstall and reinstall the product or change the template of all styles?
I think using language phrases is easier for all users to translate/change the text, don't you? It tooks only few minutes but the result is cleaner (formally text should be put into a language and page rendering code, html, into a template)
