Hi, sorry, I missed the "please create an issue" line.
I've made a PR suggesting implementing a multi delete endpoing similar to GET /2/tweets/ but for DELETE, with the other option being easing the rate limit on DELETE /2/tweets/:id so that people can quickly delete large swathes of their timeline as they currently can(50requests /15m is rather low given it was previously an unlimited call).
Happy to discuss it here if folk would prefer.
