In general it feels like there should be _a_ place that enables these resources. Checks like this make it feel like we just scattershot enabling resources in a bunch of random places instead of coming up with the design for enabling them in the right place. In any case, if we do end up landing this patch, it sure feels like it needs to move earlier in the patch series, right? This patch shouldn't hurt even without the other patches in the series but if you apply the earlier patches in the series without this one then you'll have a bug, right? That means this needs to come earlier. -Doug
