Even if js files are usually delivered compressd by gzip (which is very effective on unminimized js files), we are aware of the issue and we are working on reducing output size.
An integrated code minimizer is in the pipeline for release 1.1, and for the medium term we are working on an optimizer which cuts away unneeded libc++ initialization, which is preventing the dead code eliminator from pruning the non-useful libc++ code (which is a great part of that 1.7Mb).
So, expect big improvements in this area!
