constifying in an nighlty branch or feature gate it? (with #[const_trait])

Would a PR be welcome where most of the methods and trait-impls are constified which could either be hidden behind a feature gate, similar to how it is achieved in this or in a different (nightly?) branch?

I would happily contribute this modification, as I need to write this code for another project anyways.

I suggest you just maintain such a branch in your own fork of the repo.
