Right, that should be fixed!

But if we fixed source maps UX, we'd get a lot more bang for the cost.

But your goals include mapping line numbers to unbundled files and navigation by file name.  That sounds exactly like what source maps should do.

I think your concatenator could build the source map using 
https://github.com/mozilla/source-map/ 
pretty easy then we could find out exactly what the unwieldy bits are.
We might conclude that there is no hope or we might conclude that source
maps can be a lot better.
