I can see use cases for a delete function, but as people mention it’s all about how you manage abuse.

If a project owner really wanted they could just delete the whole repo (which includes issues et all) with no warning or confirmation from collaborators. But that’s a larger more destructive move, whereas, deleting a politically fuelled issue can be abused with far less repercussion.

Not on an issue, but I did once have a moment where I could have used a delete function on a pull request. I merged a pull request with my personal account on a repository I had only been working on under a pseudonym. From memory even resetting to an earlier commit and re-merging again with the correct identity didn’t work as GitHub kept a record of the original merge on that pull request. Which only further tied my two identities together as I tried to correct the mistake.
