is there a strong use case around passing data from a backend to a frontend, e.g. from pandas data frame on the server into a js implementation on the client side, to use in a UI? As opposed to data pipelining among processing servers.

Yes definitely. For example, the perspective pivoting engine (https://github.com/finos/perspective) supports arrow natively, so you can stream arrow buffers from a big data system directly to be manipulated in your browser (treating the browser as a thick client application). It's a single copy from network buffer into the webassembly heap to get it into the library.

Not as much because you are still paying the overhead of doubt shipping across the internet and through the browser.
