Future plans?

I have been thinking about how to ensure KernelFunctions.jl keeps working going forward with reasonable maintenance. I would propose the following:

• Make a minor release with Julia compat bumped to 1.6 and ensure tests pass up to and including LTS (just accept that this version won't work on 1.12)
• Make a breaking release with Julia compat bumped to 1.10, moving everything AD related to package extensions. Zygote integration tests would only be run for Julia versions <1.12
• Evenutually make another breaking release where Zygote support is dropped completely

The idea being that Zygote is probably not going to be maintained anymore. Maybe the default recommendation could be Mooncake and/or Enzyme. I haven't recently tested either of them though. Last time I checked Enzyme would still fail a lot of the times, and there is a related open issue https://github.com/EnzymeAD/Enzyme.jl/issues/2355. @willtebbutt what about Mooncake, is it conceivable that it would work with KernelFunctions and replace Zygote anytime soon?

No files, tests, or entry points are named. Start by reviewing the Julia compatibility and AD-integration plans discussed in this issue; done would require an agreed release strategy and validated Julia, Zygote, Mooncake, and Enzyme support.
