If it comes from the headliner than that's not an issue.
I know I've seen some other cars where the pillar cover is hinged and pops open (but not off) when the airbag deploys. So, I guess my choice of words was not quite right. I think people's concern also was that a pod would hit against the windshield and potentially impede the airbag from deploying properly.
But, if it drops from the headliner that would eliminate that concern.
