Peter,

I take your point, and I of course believe you when you say that you
meant what you wrote (ands tghat you object  to my faulty paraphrase).

Let me therefore take full responsibility for that paraphrase myself.
 AMODE(64) seems to me to be the only appreopiate way to mark an
object that is to be resident above the bar, and in particular, one
that while refreshable contains metadata, relocatable doubleword
pointers to locations within itself.

IBM has an understandably long history of omitting to enforce some
eminently reasonable constraint until that point in time at which it
judges it appropriate to do so; and marking an object, even a
read-only one, that is destined to reside above the bar as AMODE(31)
is, I think, an act of hubris.

One may well get away with it for a time, and even take pleasure in
having done so; but whom the gods would destroy they first make proud.
 (Nemesis, In the retelling of the Greek myth by Robert Graves, keeps
the list of such acts of hubris, finally meting out mercilous and
terrtible punishments for them.)
