I respect the thought and the idea and I agree with the point that those map versions are real / raw dota 1
Nevertheless , we are not the ones who decide which map version is best for the client , such decision goes toward higher RGC Officials and RGC Administrators who decide which map is being played
I saw that Thais use 6.85k dota 1 version which is nostalgic and brings back core memories of past gaming
However , dota is a game that evolves too and the development is also an important part of it , as even in IceFrog dota 1 era , the map got continiously developed
Overall I would say that the core thought is nice / worthy , downside of it is that is shifts back to the old timeline and wastes development from its developers
I still !support this suggestion
