Currently .NET Core/.NET 5 aps does not send StartupFlags in /Runtime/Start event, which are later on showed in GCStats CLR Startup Flags view. It was a super convenient way to check GC mode, with the help of CONCURRENT_GC/SERVER_GC values. Especially when analysis of sessions recorded on external, not fully controlled environments (like customer support etc.). Thise flags are reported in .NET Framework apps.

I wonder how we can return to informing about GC modes in the recorded session? Do we need a new dedicated "GC settings" event for that? Looking around various current events, I do not see any place from where such information may be received.
