You say "in a future release of macOS". I am very concerned that the full fix might only work with macOS Mojave. I'd like to point out that – as usual – not all 3rd party applications will be fully macOS Mojave compatible at its release. It is healthy to postpone a major OS update and check application compatibility for a private user, but it is always the case in enterprise environments. Mojave is a very special case! It will phase-out 32 bit support. A lot of users/businesses won't be updating immediately to Mojave because many (business critical) applications are still not 64 bit ready.

It would be highly inconvenient if the fix worked only with macOS Mojave! Please provide a full fix – not a workaround – for the latest HighSierra as well.
