I will close this as it is not mandatory to have it implemented at this stage.

We can work around this by either manually setting environment vars through adb directly, or by adding a reference to a text file (e.g., env.txt) defining the desired env variables:

DOTNET_DiagnosticPorts=127.0.0.1:9000,suspend

and configuring the app project with:

  <ItemGroup>
    <AndroidEnvironment Include="$(MSBuildThisFileDirectory)..\env.txt" />
  </ItemGroup>
