And what document is that?

Priests are ordinary ministers of the Eucharist.  EMHC's are "special" ministers of Holy Communion.  There's a distinction to be made there too - a minister of the Eucharist is one who consecrates the Eucharist.  A minister of Holy Communion is one who brings communion to another.  That's doubly so why the term "Eucharistic Minister" should not be used.

I don't see any theological point you're making here.  Just attempts to normalize something that was never meant to be normal.  It's quite clear in all the documents talking about EMHCs.
