It would probably work fine (great, even) when matching, but code that assumes String=[Char] would be completely killed on the construction side, because building Text by consing, or repeatedly prepending small chunks, is ridiculously inefficient.
Actually, pattern-matching against Text using synonyms doesn't do so well performance-wise either. The unpack-on-the-left function is uncons, which has to do work and allocate memory.
