I guess the biggest complaint after it was released was the lack of a packet manager. Not sure if that situation changed. However there was quite some buzz around it, here as well.
I think not having a package manager was pretty intentional and unlikely to change. I personally like the new import from url functionality, especially when combined with the ability to alias some of those away.
Ryan Dahl has talked about how he regrets making npm the default package manager for Node. I think its smart to have some explicit separation between framework and package manager.
Something about downloading dependencies at runtime, rather than build time, seems less safe, but in either case, you still have to download them, so maybe not.
