Duplicate messages across different proto files (dota 2)

[DragosIlca]

I'm fairly new to anything involving proto file and rpc calls so I hope everything I'm about to say makes sense.
I am trying to use the proto files defined for dota 2 to communicate with the dota 2 GC from a scala application but when i add the dota 2 proto files from this repository https://github.com/SteamDatabase/Protobufs/tree/6d7a7b5563b3f4e21d3a7487244a214202e7035e and try to compile them using Fs2Grpc I get erros such as:

steammessages_base.proto:239:9: "CCommunity_ClanAnnouncementInfo" is already defined in file "gcsdk_gcmessages.proto".

I looked through the files and it seems like the "CCommunity_ClanAnnouncementInfo" in steammessages_base.proto is just an extension for the one in gcsdk_gcmessages.proto. Should this be addressed, or are workarounds expected?
