Thanks for the feedback, Praveen and Nilesh.

Maybe I was unclear earlier: The issue was that packages would all need 
to change at once, because not only ABI changes but also package name 
and name of executable.

Good news: uglifyjs now temporarily provides virtually the new pakage 
name and installs a symlink to the new executable name, so the 
transition can be done in 2 steps where only the last (which is expected 
to affect only few pakages if any at all) need to be done all-at-once:

1) each reverse dependecy of uglifyjs.terser should switch to instead 
build-depend on terser, and should call the executable "terser".

2) all reverse dependecies of uglifyjs.terser should be test-built 
against terser v4.8 in experimental, and patched as needed.

Attached is a dd-list reverse-build-dependencies - some are maintained 
outside the JavaScript team.

I will begin now with the the packages where I am main maintainer - and 
would appreciate help handling the remaining ~40 packages.
