While I was first in favor of extending the Python syntax, I changed my mind. Float constants written in hexadecimal is a (very?) rare use case, and there is already float.fromhex() available.
A new syntax is something more to learn when you learn Python. Is it worth it? I don't think so. Very few people need to write hexadecimal constants in their code.
It is inconsistent that you can write hexadecimal integers but not floating point numbers. Consistency in syntax is fewer things to learn, not more. That said, I agree it's a rare use case, so it probably doesn't matter much either way.
