I think we can do better than that. It's fine to use high-dpi backing store
automatically for <canvas> in general. ImageData is the only situation where
it matters if there's more than one device pixel per CSS pixel, and authors
should be able to opt into taking advantage of that fact, but not be exposed
to it by default, IMHO.

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
