I understand the frustration when an OS doesnโt have the features you use in an upgrade, Iโve been there myself.
My comment is really aimed towards the OS versions we are likley to support. There has not been a decision yet on which these are, so donโt read into it too much. We want to support as many users as we possibly can - but it is fair to say that weโll be making sure it will run on the latest versions of macOS.
