This is how people will end up seeing outdated versions of wiki pages, profiles (including the info about your LN wallet!) or git proposals, for instance. The first version made it in, then they put up a wall (I got caught out with their requirement to use NIP-05, as my old npub didn't have that.) and the next versions are kept out.

I can see that people are looking at the outdated versions because they react or zap those events, and the old version is listed in my notifications.
