Sites may rely on the filter in ways that could affect legibility of
content. For instance, text on top of content that has a background blur.
Definitely not ideal.

I agree with this plan of attack. The WR implementation can help us assess
the level-of-work and timing for the non-WR implementation (vs waiting for
WR to ship everywhere). Which was essentially the plan all along anyway :)
That said, I think the last option (partial shipping) is not really an
option at all.
