It seems to me these two points are in conflict with each other,
doesn't ? It is logical if a window can be dismissed by pressing of
Esc, it must have a button with the same effect. I agree such modal
windows shouldn't have other menu buttons. For example, to avoid of
minimizing. But the button with cross is used instead of "cancel"
button - very expected behaviour.

At least I think some flag should be added to show the button on the
title bar when programmer want it.
