First) REORDERING is  useful for very common  han/hangeul labels of length 4~8.

Second) If we take into consideration the additional length of subdomains of a
IDN, the total length of  <ML-subdomain>.<ML>.com  often  exceeds
14. ANd if we think about mailbox name in ML@Sub-ML.ML.com, it will exceed 20.
IN that case, the Sum of the lengths of  saved characters in each substring in ML@SUB-ML.ML.com will be great, around 15~20, i guess.

will answer some of your questions.
We should not attempt to draw an upper limit on future  applications of 
han/hangeul IDN domains by imposing unfair disadvantage on max length 
of Han/hangeul labels .
