> as it forces a specific concurrency model on the consumer

I found your excuse above is really nonsense. when your program is in Golang, you've already picked side, the concerned concurrency model has already been chosen by the user.

we are not talking about one of random concurrency models, we are talking about channel based sychnronization and communication in golang, if you don't want that and consider it as an issue, you shouldn't be using golang in the first place.
