Yeah. (I got the list by searching for "named error" in the spec, which  
matched a bunch of stuff that fires error events, but the list is very  
likely not exhaustive.)

Could you file a bug to that effect?

No use case for not doing it. I'm fine with doing it if there's a use case  
that warrants doing it, and we can keep the platform consistent with  
errors elsewhere.
