I feel somehow this decision should be made in command buffer and propagate
here, but let's land this for now.

Yes. I think it just exists this way using the static checks because we don't
have a context, or necessarily even a decoder (and which one should we look
at?). And we want to init the cache early so that it can receive the shaders
from the browser from disk.
