I think many of us would want to make that second statement a MUST, both in the interests of better interoperability, and to maintain the environment that has led to the current flourishing of webfont availability, services, and use.

Exactly where such a requirement is specified may be less important than that it _is_ specified as a normative requirement for user agents. This has always been understood as part of the "WOFF model" in which many font providers - large and small, commercial and otherwise - agreed to participate, seeing it as a workable compromise that balanced competing and sometimes contradictory requirements and desires.

If the WOFF spec, the CSS3 Fonts spec (which I think is the most sensible place to specify the behavior of @font-face, with reference to another spec for CORS or From-Origin as appropriate), or some hypothetical Webfonts Conformance spec requires this - which is the behavior the Working Group has agreed on - and Samsung chooses to ignore this aspect of the specifications.... well, that would be regrettable. But such a lack of conformance on the part of a particular vendor would, IMO, be a lesser evil than to undermine the entire model that enabled the current blossoming of webfonts, and risk thereby losing the trust and goodwill of many in the font community.
