I did not find any occurrences in a large sample of IDNs on the Web.

>> The character U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW that the
>> review is related to has today the derived property value "PVALID" in the
>> current proposal discussed in the IDNABIS working group.
>> Because of this, I encourage interested parties to respond to the
>> questions stated below.
>> I am confident IETF and Unicode Consortium will be able to synchronize the
>> two standards so that there is no incompatibility issues.

>> > PRI #147: Proposed Deprecation of U+0673 ARABIC LETTER ALEF WITH WAVY
>> > HAMZA BELOW
>> > The UTC has recently approved a proposal to encode an ARABIC WAVY
>> > HAMZA BELOW for a future version of the Unicode Standard. That
>> > character is used productively in Kashmiri and other languages, and is
>> > applied to letters other than ALEF. The intent is to deprecate the
>> > existing character U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW, in
>> > favor of the sequence of an ALEF plus the new ARABIC WAVY HAMZA BELOW.
>> > (Because of normalization stability constraints, a canonical
>> > equivalence relation cannot be established.)
>> > The UTC is seeking feedback on whether U+0673 should be deprecated
>> > when ARABIC WAVY HAMZA BELOW is encoded. Pertinent information would
>> > include data on how widespread usage of this character is. Note that
>> > deprecation of a character does not mean removal of that character
>> > from the standard; it merely constitutes a strong recommendation not
>> > to use the character.
