I generally agree with your points in previous emails, but I still think
it is necessary to add a new chairless non disjoining hamza, though one
can get the required behaviour with smart font technologies, it will
break existing text where the user is expecting a different behaviour
(thought we might consider it wrong behaviour), and it will be
contradicting with the behaviour assumed by Unicode, or am I missing
some thing here?
It is also noted that the behaviour of hamza not breaking joinable
letters is now restricted to Quranic text (and may be other historical
texts?), so it is safe to consider it a different character. The same
goes with Farsi yeh (U+06CC) Vs. Arabic yeh (U+064A), while both are
exactly the same character with the only difference is that Arabic yeh
has dots in the final/isolated forms, old Arabic texts (and modern
Egyptian) assume the same behaviour as what Unicode calls Farsi yeh.
