It would be nice to be able to disown a comment, instead.
Comments that accidentally reveal personal information, that would be a nice use-case for deletion. But on the other hand, nothing can be deleted from the internet, so having the button there could add a false sense of security.
A file on the internet obviously could be backed up by anyone, so deleting things from the internet does not verifiably restore your privacy.
A file on the internet might not be publicly accessible in the future. But that doesn’t mean it hasn’t been backed up privately.
It is the worst of both worlds.
Probably it won't, though, for most people.
Posts made after the API access was removed would not be in Pushshift.

In practice, if someone on Reddit deletes their post, it's extremely unlikely you'll be able to recover it. It's not a probability of zero, but pretty close to it. You could file a lawsuit and then Reddit will have to find it, but otherwise, it's gone.
I doubt that unless it's criminal evidence or something
