There are two gems: rubygem-coffee-script and 
rubygem-coffee-script-source and they have the same authors [1, 2]. 
rubygem-coffee-script-source carries the javascript code of coffeescript.

By coincidence Jeremy Ashkenas is author of coffeescript and 
coffeescript source code containis Rake script [3] which generates 
rubygem-coffee-script-source.

This is to explain who is upstream of what. Nevertheless, the upstream 
question is orthogonal to bundling question.

Since there was/is no better place to store JS files, since there was no 
standardized way how to execute the code at that time, since we did not 
duplicated any system library, it was pragmatic to keep the JS where it was.

No doubt about it.

Definitely, that is why I am participating in this discussion.

Unfortunately, they are coming with nodejs packaging guidelines [4], not 
javascript packaging guidelines. And better to watch coffee-script 
review [5], since this is not node package but JS package IMO. There 
should not be "Requires: nodejs" at all.

Definitely.
