> @nikic Do you think it'll be reasonable to revert the changes to onlyAccessesInaccessibleMem and onlyAccessesInaccessibleOrArgMem and land the patch as is? That will temporarily break the link and make it easier to rollout the support for target_mem. Perhaps also adding a note to the LangRef saying the target_mem locations must not be used outside of internal testing?

Possibly -- could you clarify what the steps after that would be?
