Since a SHOULD requirement is optional, I don't think it necessarily raises critical patent concerns. For example, Apple's experimental implementation of <video> does not support Ogg Theora. That being said, I think it is important for the W3C to explore this issue. And Apple would be in favor of removing the SHOULD as well (we think it is unhelpful to say implementations "SHOULD" do something that some of us "CAN'T"), but we do not consider it a showstopper requirement.
