Is this just criticism of the "isomorphic" term?

I'm not a fan of it either ("isomorphic" already has a different well-defined meaning in CS), but it does seem to have some traction now.

Perhaps you have an alternative term you'd prefer these frameworks used?

I've seen "progressive javascript"[1] and "heterogeneous javascript". Both of which are much better IMHO.

Agreed, both of those are better. Hopefully one will gain traction.

Thanks for the link, good to know people are thinking about the naming issues.

I've seen "split rendering" a few times.
