Post History

> We don't care about /.../ edit history.

I'm going to disagree here, actually. Edits can be substantial in their own right, introducing new content from users other than the original author of the post. (The golden rule for edits Somewhere Else is to always preserve and respect author intent, but there have been occasions when this still meant pretty much rewriting the post from scratch.) While indeed this isn't attributed to each individual user in the current revision view of a post (which would get messy real fast), it *is* attributed in the post history to the user who contributed each piece, and that content is normally available only under an attribution-required license. (Some users do things like write in their profile "my contributions can be used under License X", but there's no standard way to indicate that the way there is on Codidact where each individual post has an explicit, specific license associated with it.)

For that reason, while we might not care about revision summaries or timestamps or the fact that users might have changed their display names since (the current one is probably good enough for them), to the extent that the information is available, **I think we *should* aim to preserve information about at least the edit sequence and which user made each edit.**
