It seems that some people think that IAST also defines a Cyrillic
representation, so I think the 'Latn' is justified.

Well, as the two systems are international standards (the 'i' in
'iast' and 'iso'), it should be hard to tell whether the intended
audience is English, German, Japanese or whatever.  The what of the
underlying content is contained in the extension - in this case the
'sa'.
