How to work around std::get<>()'s lack of concurency specification

Push a proposal for std::get<>(std::tuple) to provide guarantees similar to std::vector<>, and document the fact that the code is only valid as of a yet unreleased version of the the standard.

I think this is the way to go, as it provides value for the entire C++ community and should not be a burden on implementers. It is also an excellent opportunity to write your first proposal.

I suggest doing that, and for now assuming that this will work, even though it is UB. If your software is super-critical (e.g. flight control system) and you want to be 100% sure that you are not relying on something that could break in the future... then implement your own tuple.
