I am aware of these two I-Ds, which looked at making use of that space:

https://tools.ietf.org/html/draft-fuller-240space-02
https://tools.ietf.org/html/draft-wilson-class-e-02

I believe the main reason they did not progress was that the vast
majority of deployed devices would barf at those addresses, which
would raise support costs for network operators beyond those incurred
by other approaches to providing continued IPv4 connectivity.
