I forgot to mention that I'm still trying to figure out how to add the attribute. I know mechanically how, but AFAIK there isn't a target feature or anything we set when enabling SCS(except for Zcfiscs), so if there is an obvious way, a pointer would be welcome. I think that's something we need to set in STI, so I'm looking into changes to allow that.
