I pushed this list taken from UDD database (reverse build depends) +
"apt-cache rdepends", just to help to understand the impact of this bug.

I do not have a theory, just want to help (I'm not uploader of any
package concerned). So ignore my mail if it is not clear/useful.

The fact is that today, it is not possible to have both webpack (or some
other packages) and uglifyjs on the same machine.
