Why not just bypass the upper feedback divider resistor? That's what >>>>>we do.

Wouldn't trust any direct connection between an integrated circuit
pin and a sensing point, particularly in the presence of noise.
In lots of reg chips, the connection is internal, out of your control.
Also don't trust internally generated reference currents. Why? >>>>Probably because it's just one more added complication and source
for error, over which the end user has no control.
If it don't work, don't use it.
