With MSBuild.exe, I can set theSharedCompilationId property and later runVBCSCompiler.exe -pipename:"$(SharedCompilationId)" -shutdown to terminate only the Roslyn compiler server that was started for this ID. Is there an equivalent feature fordotnet build-server shutdown?

It looks like theDOTNET_BUILD_PIDFILE_DIRECTORY environment variable could be used for something like that:

However, from#9302 and#9303, it seems the environment variable is not used by all build servers; and even if they use it for PID files, they might not use it for the actual communication.
