Is there any way to dig coop mutators from replay?

Actually there are three types - Weekly, Custom and Brutal+, only weekly are displayed during load, but still can't find anything relevant in replay.

I don't play coop, but I believe mutators are injected as extension mods. So they should be listed in cache_handles.

Thanks, this helped a bit, but only for weekly, which are injected during/before game load. I can't see them for B+ and Custom games, do you have any idea where this could be?
also interesting is that detailed_info['m_syncLobbyState']['m_gameDescription']['m_hasExtensionMod']
has different values .. true for weekly and custom, but false for B+
And another thing is .. is there any list of all extensions anywhere?
