Can the elliptic-curve hazmat feature be removed?

[mgeisler]

Hi there,

While vendoring this code, an internal reviewer asked me about the use of the hazmat feature in elliptic-curve: it looks unused.

Would it make sense to remove it, or do you have it for consistency with the other crates?

I believe you're correct. It previously gated a small amount of functionality only intended to be used by implementations of elliptic curves, but those have since been removed.

Alright! I crated #1599 for this. It will be a breaking change, but maybe that's okay since the crate is at version 0.14.0 right now.
