We're moving forward because there is clear demand. The texture-formats-tier1 feature capabilities have been a topic of discussion for years. See https://github.com/gpuweb/gpuweb/issues/3001#issue-1257513985 or https://github.com/gpuweb/gpuweb/issues/2630 for instance. > > On the other hand, I read the WebKit bug as positive rather than "no > comment" so there is that. :) > Indeed.
