Assets should not be minimized/compressed

[marcandre]

It's the job of the asset pipeline to minimize / compress / etc the source.

Among other things, we want uncompressed sources in development, in case we need stepping in the code...

I was looking for this as well, but CKEditor needs to run a bash script during compression
See http://docs.ckeditor.com/#!/guide/dev_build

Never distribute the source version of CKEditor to production websites. There are serious performance implications of doing this. Instead, you must create a CKEditor "build" or "release version" (in contrast to the "source version"). It is an optimized, production-ready CKEditor distribution.
