I assume twitter will absolutely show a 'this tweet has been edited' button that brings up all the revisions of it, opens itself up to too much bait and switch nonsense otherwise.
They've done the user centric research & every user says they want to be able to change what they say online & escape their bad mistakes. The team has resounding data pushing them this direction. And it will be immensely immensely detrimental to the platform/service/medium.
It's like the "Hidden replies" feature [0]. Sure someone can maliciously use it to hide valid criticism. But in doing so, they're essentially doing a public curation of "these are the replies which really rankled me"

i.e. more like a built-in 'delete and re-post', but with preserved metrics.
