It bothers me that the new text makes no mention of the gotcha involving 
U+0387 GREEK ANO TELEIA which has a singleton decomposition to U+00B7.  
This is not the place to go into the unfortunate historical reasons for 
this situation, but it is a disservice to the read to not mention that 
there are potential problems involved with U+00B7 and handling Greek text.

Opt Subject: ID_Start, ID_Continue, and stability extensions

See this email thread: http://www.unicode.org/mail-arch/unicode-ml/y2014-m04/0138.html

In summary, http://unicode.org/reports/tr31/#Default_Identifier_Syntax should 
make it more clear that “stability extensions” means `Other_ID_Start` and 
`Other_ID_Continue`, respectively. At the moment it lists an incomplete formula: 
it’s explicit about all the categories and properties to include to form 
`ID_Start` and `ID_Continue` _except for those_, for seemingly no good reason.
