Since the question about absolute positioning of windows comes up every now
and then (and probably will continue to do so for the next few years), I
thought about a possible way to fix this.

We could create a new interface, that puts an unrotated rectangle around a
window (which could be transformed in whatever way), that is just big
enough to fit in the whole window. The upper left corner of this rectangle
could then be defined as its "position", which could be read and set by the
user. The size of this rectangle could also be of interest of the user, but
of course not be set.

Since a window could be on multiple outputs, there would be the need for
one instance of this interface for every output and every window. These
could maybe be created and destroyed with events (whenever a window appears
or disappears on an output).

This is not 100% thought through, but maybe a starting point.
