I can't give any specifics, just the my general
observation of watching this play out in real
life. What you're missing here is not whether
it _could_ be included, but whether including
it means that perceived revenue generating
features will have to be foregone because of
security. The unfortunate fact is that
security is not generally seen as an offseting
feature; it's just a cost, not a product
differentiator.
Half of the problem of getting pervasive crypto
is just getting it into things. Lowering the
energy barrier here would change a lot of the
dynamics that I've seen, and as I said to Dan,
I work for a company where bloat isn't one of
the major cultural evils -- unlike consumer
electronics companies where those pennies add up.
