That honestly surprises me. When text is central, that sounds like when you most need to be able to organize your data without worrying about whether a delimiter might occur in some content...
Note that I'm not saying that a stringly typed language mightn't, in some cases, be the best choice. Just that it will be the best choice for reasons other than being stringly typed, and a language that allowed better organization of your data while offering similar affordances would be an improvement.
