* 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
me.
* 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
minification.
