Sendable conformance and strict concurrency

[AvdLee]

Opening this issue to check-in on your plans for concurrency support. Instances like Variant are currently open classes and don't conform to Sendable. This will lead to warnings, and potentially even failures when Swift 6 arrives.

See: https://www.avanderlee.com/concurrency/swift-6-preparing-your-xcode-projects/

Are you working on concurrency support already?

Hi @AvdLee Thanks for bringing this up. We do plan on supporting Sendable protocols on our classes where possible.
