I think in the vast majority of cases people don't actually care about deleting their content, they care mostly about disassociating something from their identity. Maybe they asked something dumb or controversial years ago and they don't want it to show up with their name on it.
I think maybe there should be more of a trend of websites not showing usernames next to posts and just an identifier like "Purple" that changes when you post on a different thread/post so you can still follow the flow of a thread but not be able to link it to unrelated posts from that person.
I cant say that knowing the usernames of posters has ever helped me on stack overflow. Mods would still be able to see it but regular users and scrapers can not.
