This doesn't comply with the Degrade Gracefully design principle. Is
this feature so important that it's reasonable to change table parsing
(one of the annoying parts of the parsing algorithm) in a way that'd
make the modified algorithm yield significantly different results than
existing browsers? Have designs that don't require changes to table
parsing been explored?

A change to the HTML spec proper *if* we decide that changes are a good idea.
