I've written a clj/cljs app with source sharing, and there are many downsides. Tooling, lack of progressive enhancement, debugging, download sizes.
I feel the benefits are worth it for my use case, but it's not all roses.
But hiding the client server architecture is just a bizarre criticism to me, because it's not at all what writing one of these projects is like, and I'm not sure how you're even getting that impression.
The degree to which you share code depends on how much functionality you are replicating, and is code that you would literally be cut paste porting if you were using another toolset. Or just avoiding writing altogether, like speculative updates.
Just because you can theoretically attempt an antipattern doesn't make a tool bad; you can write shit in any language. And many do.
