PS2:
> adding julius werner, can you please quote the reason for not using gscvd on CR50 devices by default […]

GSC verification is a feature that will first roll out with Ti50. There is a Cr50 implementation but I believe(?) we ended up deciding not to use that. I think it was added to guybrush here before that decision was made, so taking it back out now seems reasonable.
