Thats a shame. It seems like a "no brainer" to me
I assume its pretty easy for a hacker to analyse an App built with PGB for distribution and see the code exactly as it was submitted by the developer.
I will have to get to work on a .bat script to do it myself. I guess:-
* recursively copy files to a build directory
* traverse the build directory hierarchy recursively
* run a minifier command such as ajaxmin.exe (MS) on each .js file
