  * some minifiers produce broken results sometimes for some code.
    (as already mentioned earlier).  The use of different minifier
    may reveal bugs in upstream code or in Debian packaged minifier
    and/or JavaScript code.

  * Different versions of minifiers produce different minifications.  
    Maintaining multiple versions of minifiers around for the purpose of 
    being able to reproduce upstream minification seems quite wrong to 

  * Some minifiers exist as web services, not (DFSG-free) local tools.

Some of above are not arguments against _trying_ to mimic upstream, only 
in the likelihood of success.  But as a principle I find it to be a 
wrong aim for Debian to mimic upstream regarding minification - whether 
or not it is "appearance" only: The purpose of minification is 
efficiency, and we should pick the most efficient minifier available to 
us, no matter if it happens to produce exact same results as upstream
