Not really. General notes, I'd make:

 - Many languages don't require anything but an appropriate
   font.

 - For more complicated languages, support is more of a matrix -
   individual support needs to be written for different font 
   backends - a fair number of languages (South Asian languages) 
   are only supported fully with traditional X fonts.

Yes

Some support for polytonic greek. Accent placement may not be optimal.

> Cyrillic  supported for Russian. What about other languages?
Yes, all languages.

Yes, for all languages. (Haven't actually tried Ladino...)
Support for combining marks better for X backend. 

> Arabic  In process
Yes. (Pretty good support both X and Xft)

[ Don't know where you got "in process" for either Hebrew or
  Arabic. While the support could be improved, as always,
  it's quite complete and functional. ]

All languages in the BMP that don't require special support will
be supported. (So, Thaana, Braille, Math, APL...) Syriac would
need special support. Forget of Deseret is BMP or not.
