For the record, my view is that we want mixed ltr and rtl text to feel
good. The font will not be used exclusively in any one language, it will
mostly be used in mixed environments (a tech-savvy audience will use the
web a lot). Therefor, optimising for mixed environments is reasonable,
and likely trumps single-language conventions. So I would slant to the
right for Hebrew, so mixed Latin and Hebrew italics feel natural.
