One of the use cases for named tuples is to have them be automatically created

Sometimes (but not often), those can have a huge number of columns. In Python 2.x, it worked just fine -- we had a test for a named tuple with 5000 fields. In Python 3.x, there is a SyntaxError when there are more than 255 fields.
I'm not sure why you think this is new. It's been true from at least 2.5 as far as I can see.
