> # '''['''10:44''']''' <mkwst> terinjokes: SRI only applies to those elements because the current spec is basically a test to check that we can actually verify integrity on the wild and crazy internet.
> # '''['''10:44''']''' <mkwst> terinjokes: Basically, they decided to do the simplest thing possible, make sure it works, and then expand it based on that experience.
> # '''['''10:45''']''' <mkwst> terinjokes: Tacking `integrity` attributes onto other elements as necessary is an obvious next step.
