Will notarization succeed with reaper_host_i386.app inside our .app bundle? If it does not, that means we'd have to have a separate download with reduced functionality for Catalina users.
Will we have to (eventually) build with Xcode10_/macOS 10.14 SDK for the hardened runtime? I know this requirement was delayed but will it be an eventuality? I've never been able to get Xcode 10 to work right with legacy code.
Plug-ins should work fine in any case without notarization, since we will request the relaxed dynamic library loading entitlement (except for now in non-notarized Audio Units, since I guess the component manager uses the hardened runtime).
