Expose SIMD feature

[daxpedda]

curve25519-dalek exposes a SIMD feature (nightly only), is it in scope for opaque-ke to re-expose this?

Alternatively, of course, consumers can just activate this feature themselves by adding curve25519-dalek as a dependency in their crate.

Hmm, no strong opinions about re-exposing this versus not. It seems like applications which would like to take advantage of the SIMD feature would need to add curve25519-dalek as a dependency (in which case they could just turn on the feature themselves) anyway, so I am leaning towards not re-exposing this.

But if you have a specific use-case in mind that would benefit, would love to hear it!

There is no specific use-case in mind, I consider it a good practice is all:

• clearer dependency tree
• less duplication (update has to happen in only one dependency)

As you can see, this is a very shallow and subjective list 😆.

EDIT: you can close anytime if you don't agree, otherwise I'm happy to make the PR

[kevinlewi]

Fair enough -- looking forward to the PR!

[daxpedda]

I guess this should be done at a later point, the feature is currently broken:
dalek-cryptography/subtle#85

[kevinlewi]

Closing for now, in that case
