That's the foot in the door, if you allow it.

There are several things in Dired that can be
hidden in one way or another.  So far, they're
NOT all enabled willy nilly whenever you turn
on `dired-hide-details-mode' - fortunately.

You can hide subdirs (`$', `dired-kill-subdir',
`M-$'), lines (`dired-kill-line'), whole trees
(`dired-kill-tree'), uninteresting files
(`dired-omit-mode'), image thumbnails
(`C-t C-t'), etc.  And in Dired enhancement
libraries there are more hiding possibilities. 

Instead of requiring evidence to "break the
connection" - which is a brand new, _proposed_
connection, you ought to require evidence for
why this particular proposed hiding should be
connected to `dired-hide-details-mode'.

Just putting "hide" in the name of something
doesn't, logically, connect it to something
else that has "hide" in its name.  I'm quite
surprised to hear such a rationale from you,
frankly.
