We cannot simply copy things to $TEXMFVAR.  In many cases it's
required to remove an older version of a package.  There are many
examples.  What comes into my mind is vntex, where the name of a
directory had been changed recently.

We have to *replace* packages. It's not sufficient to put a newer
version somewhere else in the file system.  I also don't understand
why anybody wants to update a system which resides on a filesystem
he deliberately made read-only.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
