Do you have this list available yet?  I'm curious about these points, 
and others.

I thought SIN was indicated sometimes by a SAMEKH written above the 
letter.  How would putting a SIN (which is just a SHIN with a dot on the 
left instead of the right) on top of the letter be any improvement (or 
difference) over just putting the dot on the left of the base letter in 
the first place?

OK, here I'm confused.  Why do we need copies?  Unicode doesn't like to 
encode redundant things, and it only makes for messes (when do you use 
which ZIQAA?)  If we have the characters in the BMP, we don't need them 
in the SMP.

So additional Hebrew "letters" that take Arabic vowel-points?  Makes 
sense; I saw some of that with Samaritan (particularly with DAMMA). We 
should probably just use the Arabic vowel code-points though.

When you say "superscript" (or "subscript"), do you mean "spacing 
character that's written small and raised/lowered"?  Or do you mean 
"combining character that's written above/below another character"? cf. 
the difference between U+2071 SUPERSCRIPT LATIN SMALL LETTER I and 
U+0365 COMBINING LATIN SMALL LETTER I).  If the former, is there a 
reason this has to be done as plain-text and can't be handled by 
higher-level markup?  Probably every major script has been written small 
and high in some places, but we don't have superscript versions of every 
letter in Unicode.
