I think you may have been in crypto for too long. If you ask the average joe on the streets to name a cryptocurrency, almost all could name Bitcoin. I don't think you could say the same about any other one, even Ethereum. Until the large public is aware of more than Bitcoin then we can stop calling them altcoins. Plus there are very few ETH pairs out there. It is definintely a tiny minority of all crypto pairs able to be traded.
