Hi @matt-ramotar
Are there any plans to support this in the near future?

Thanks!

Hey there - Thanks for reaching out! @digitalbuddha is working on resolving the last remaining breaking changes to Store4. Once #559 goes in, we can add this along with #554 and #555. My ballpark estimate for merging these changes is mid July. Does that sound OK? Let us know if you need it sooner and we will do our best

[jsilva05]

Thank you for the quick reply.

Sounds good! We started to migrate some of our usecases to store5 to see what would be the changes needed. We have a couple of cases where we need CacheOnly but we already have a workaround in place and we can keep using it until this is ready.

Hi there! Is this under development? It seems that #559 was merged in some time ago. If it's not in progress, I'd be happy to take a look at it

Hey @wbrawner - No progress yet. Awesome! Happy to review
