Wouldn't that mean that connection will be open until the iterator is closed?
Considering that now it is used only in remote.all, which was supposed to create a generator in the first place this change is good.
I am just wondering if it will not become fragile if, in the future, we will start to wrap some logic around this method (for any reason). But also, I am worrying prematurely here. I just wanted to ask this and keep in mind for the future.

Yes, this will hold the connection open. Not sure this will be an issue.
