Indeed, that will change the landscape in cryptoland :)
But there are existing solutions in place as well - Segwit, transaction batching - but for political/economical reasons large exchanges and service providers - like coinbase - are reluctant to implement them, so they are "spamming" the network with massive transactions and as a result, basically attacking the bitcoin network. Do not use any service where these features are not implemented, it's a clear indication of their true colors and attitude.
