Sometimes, "З" and "Э" (and corresponding small letters) may have descenders, 
for example, in the "Elizabeth" typeface.
Other letters can be added to the above lists ("ГИМНТ")

See above.

Also, you may want to add two blue zones for descenders, based on "ЦЩ" and "цщ" 
(in this case do not forget to check for possible blue zone overlapping). These 
descenders are actively used in extended Cyrillic.
