There are many use cases where its vulnerabilities are not a weakness, as e.g.
in data mining, probabilistic string and pattern matching and many
more. So why remove it (and breaking a lot of software)?

The point is that its use as a cryptographic hash should be abandoned,
but not its use in general.
