I know backward compatibility with Java 5 is important for the clojure world, but I would love to see streams and invoke dynamic implemented in a "Clojure 2.0".

I would love to do it myself, if someone would pay me to do it :)

Streams are an API built on top of the Spliterator[1] abstraction, which basically gives a collection the option of partitioning an iterator into two, allowing parallel traversal of both partitions and thus parallelization via fork/join. Clojure already does something very similar with reducers[2], which are pretty much the same as Java streams, but implementing the reducer protocol to employ spliterators should be rather simple.

Why is that? (I googled but didn't find anything relevant.)

Since Clojure 1.6, Java 6 is the minimum requirement.

I'm sure there is a discussion somewhere, but I expect that there are quite a few people who run Java on commercial J2EE app servers and the like which don't officially support newer JDKs.
