Swift-Syntax Prebuilts for use in iOS apps at run-time?

It seems, per [Preview] Swift-Syntax Prebuilts for Macros , that Swift-Syntax Prebuilts are expressly intended to allow uses for macros. If an iOS library depends on Swift-Syntax for doing things at run-time, then it seems the toolchain will ignore the pre-built and build Swift-Syntax from source. If you are using Swift-Syntax for macros, it seems to ignore the prebuilts for that too, building from source for both macOS (for macros at compile time), and for iOS (for use at run-time). In my case...
