The OSM wiki also claims a fence must be a line.
What physically is this 'screeching fence'?
Is it in the middle of the road like a cattle grid, or along the edge of
the road?
A single pole with the device on it?
Or is it 2 poles on opposite sides of the road with devices mounted one
them?
Or is it a series of poles along both sides of the road with devices on
them?
While for simplicity using a node on the road is good for the mapper it
is not good for the data consumer when used as a 'fence'. I would think
it is more of a different kind of 'cattle grid'. If you want something
that 'works' then use barrier=cattle_grid with method=acoustic, assuming
this will be used instead of a cattle grid and possibly a replacement in
future ... square peg in a round hole.
Or come up with something new
barrier=animal
method=acoustic
???
