fantasai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-inline-3] top metrics for non-Western non-CJK writing systems with obvious top edge ==
Both Thai and Hebrew are writing systems with strong top edges (similar to Latin/CJK).  But while OpenType defines multiple top edge metrics (cap-height, x-height, ideographic, and hanging), none of these necessarily coincide with the Hebrew or Thai top metrics, which in a given font will often fall somewhere between the x-height and the cap-height, but not consistently the same place across fonts.

If `initial-letter-align` and `text-edge` are to treat these writing systems as equal citizens of the Web, we need metrics for them in OpenType, and we need values for them in CSS that will select those metrics.
