Hold up, I think we have a discrepancy regarding what we are talking about.

I’m not thinking of anything user facing. The ux would be exactly identical to what is publicly observable on reddit already. I’m talking about the possibility to dump any change to comments or posts into a cold data store for later analysis. We don’t have to question or think how many users would make use of it, we can count the fraction of comments with an “edited” label on reddit.
