Preconcurrency in Umbrella Frameworks

I have an app module that imports the AppFoundation framework, which is an umbrella framework containing commonly used frameworks in the target app.


//  AppFoundation.swift
----

@_exported import Foundation

#if DEBUG

@_exported import AppMocks

#endif

@_exported import AppModels

@_exported import Alamofire

I tried using @preconcurrency for a framework (AppModels) that’s imported and exported within the umbrella framework to silence compiler warnings in the app module related to types from that framework that aren’t Sendable-friendly. However, I ended up having to use @preconcurrency on each import in the app module instead of a single @preconcurrency import within the umbrella framework.

My question is: Is it possible to use @preconcurrency inside umbrella frameworks and have it propagate to modules that import the umbrella framework, or is this not supported?
