While reading page 13 of John Hudson’s IUC39 presentation [1], I was
wondering if HarfBuzz can handle script, language and direction
properties the same way it handles optional features; i.e. instead of
sending HarfBuzz buffers that has a single script, language and
direction, one sends a single buffer for the whole paragraph with
arrays of script etc. ranges similar to hb_feature_t ranges and let
HarfBuzz do its magic on it, allowing for any cross boundary lookups to
be applied as the required context will not be lost.
WDYT?

While this might be nice in principle, I suspect it would be of limited
value in most real-world use cases, because it's very common that
script- and language-run boundaries also turn out to be font boundaries.
(This is much less likely to be the case for language changes within a
single script, of course; but it's also relatively uncommon for content
to actually be marked-up for language at this level.)
So I'm not sure it'd be worth the added complexity for the few cases
where it could actually be applied.
