It has problems, as mentioned elsewhere in the thread:

 * It is easy for authors to not include any fallback, which makes it 
   worse than the <input> equivalent.

 * The fallback and non-fallback controls have different names.

 * The datetime types don't really need comprehenive fallback, given
   that the three cases that they could replace are:
     1. Text inputs, which would be improved, not hurt, by the new types,
     2. <select> controls, which do not need to be replaced at all, and
     3. Complex JS widgets, for which declarative fallback is not needed.

...not to mention the extra complexity and the implementation difficulty 
compared to just using a new "type".
