[Qgis-developer] Expression to get label reference point X and Y for use with geometry generator (make_line) ?

Hi QGIS !
I am playing with data-defined label position, with 2 column label_x and
I use a geometry generator to draw the line between the label and the
feature centroid, like
centroid( $geometry ),
make_point( "label_x", "label_y" )
It work pretty well (with some rectangle background under the label text),
but it is obviously only active when the label_x and label_y fields are not
NULL ( when the label is pinned )
I would like to draw this line for any features (perhaps depending on this
line length). So basically, I would need 2 new functions $x_label and
Anyone has tried to achieve this ?
