Keeping only the most recent data might be tempting, but I'm not sure that's the best practice. There could be valuable historical information in the older data.

Okay, I think I've got this. The property that enables custom LWCs to override OmniScript elements is the "LWC Component Override" option. That sounds like the right answer to me.

Okay, let me think this through. The question is asking about legislation that protects consumer rights regarding information collected through digital marketing. The Data Protection Act sounds like the most relevant option here.

You know, I'm kind of surprised that 'removing the data source from production' is even an option. That's like going nuclear on the problem! Let's keep things sane and go with the codebook approach.

Exactly, Candida! Keeping the historical data is crucial, and the codebook will be a lifesaver. I can just imagine the chaos if we started deleting old data. 'Wait, where did that crucial piece of information go?' Nope, not for me.

Placing old data in new fields? That just sounds like a recipe for confusion. And keeping only the most recent data? What if we need to reference historical information? Nah, the codebook is the way to go.

I agree, the codebook option seems like the most thorough approach. Plus, it'll make it easier for future developers to understand the data and its history. I'm not a fan of just removing the data source from production - that feels like we're sweeping the problem under the rug.
