What is your evaluation of this position?

The above position (white to move) occurred in an actual game WT vs. GM Nick
Defirmian.
As a human player , my evaluation based on whites king locked and poor pawn
structure should be at least -400 points.  A mate in about 50 moves can be
predicted with a forced rook exchange  and winning a pawn with zugzwang. These
can be accomplished by marching the black king to the second and rook on the
first and than get the king to h5, forcing whites bishop off g5 with zugzwang.
Since the kings mobility strength is equal to at least one rook,the bishops of
opposite colore rule does not apply here.
My question to programmers is: “ Are programs being blindfolded by BOC and
Kingsafety rules”?
In my opinion,a locked king should result in a loss of -400 evaluation points
until an escape is found.

PS,all currently top rated programs are useless and or missleading for
use of analysing such positions. Is it time to add or modify rules for
BOC and Kingsafety?
