due to "won't" being the contracted form of "will not",i don't see why it shouldn't be spoken
Compare it to "do."
Do not you find this structure bizarre?

Don't you find this structure bizarre?
In contemporary English, "don't" and "won't" introduce questions. In older English (probably until the mid-19th century), and in the
most refined registers, you may encounter "do you not / do not you" or "will you not / will not you."
Abbreviate the question words for negative questions. In contemporary English, there's actually a difference in meaning between:
Don't you think she's pretty?
and
Do you not think she's pretty?
