Your menttion of Stability are presume the variations of frequency
distribtion of characters in a script block. But, as i stated before,
the influence is marginal and REORDERING is not optiomal solution,
but sub-optimal solution that have clear benefits for a long time.

Please read  2500-years-old chinese classic books, then you can 
find there has been no great change in frequent han characters.
Really!!!

You should suggest the proof that the frequency
change will be great in the future and hurt the statbility of
REOERDERING tables.

You missed what the above examples really shows.
Please think again the sum of length of saved characters in
ML@SUB-ML.ML.com.
