I'm also concerned about performance here; I worry that any browser implementing the rules in http://dev.w3.org/csswg/css-text-decor-3/#line-position that turn this "may consider" into a "must consider" will end up becoming too slow on pages that use text decorations on large spans of text (e.g., a long page that underlines the whole body); I think it's entirely possible that the performance regression will be severe enough that the whole thing will end up unimplemented. (I certainly wouldn't encourage a developer to spend time trying to implement it, because I don't see it ending well, and I think we have bigger problems to solve.) -David -- 𝄞 L.
