I never ever said or thought that these characters are unimportant, or 
that it would be okay to make it difficult for speakers of Hebrew or 
Arabic to comment their code in their native language.  I only suggested 
to make these characters stand out by default, and only in source code 
files, given that they have potential security implications.  Just like we 
make no-break spaces, thin spaces, hair spaces, and so forth, stand out. 
That doesn't make the life of those who would like to comment their code 
in their native language more difficult.  Even more so if it transpires 
that these characters are in fact used rarely, even by those who use RTL 
languages in source code files, which is why I asked to see a real-life 
example of such a use.
