We've changed the spec to address one-off breakage on less prominent prominent sites than united.com, and the Hypelatex breakage affects multiple sites. (And on the topic of pragma no-cache in meta we even have a bug open without data of any specific real site breaking.)

I think in this case the spec change to hoist to <head> would be super-simple: One "process according to the rules the foo mode" case. The implementation would add a few lines of code but nothing dramatic.

However, I'm starting to prefer leaving the parser unchanged and taking into account the first <base href> (or <base target>) in the document. This would be a true spec simplication: Saying "first foo in the document" is simpler than saying "first foo that's a child of bar". Looking at the Gecko implementation of <base href>, it seems to me the implementation could become a couple of lines simpler or stay at about the current level of complexity.
