As the first optimization, we added a pagination for it. But it was not convenient for everybody to use. The next step was to add a `Show full blame` button that showed the blame view without pagination. It provided an option `no_pagination=true`. Finally, we added a streaming mode that replaces `no_pagination` step completely. Blame streaming was fully enabled in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/119752+. **Proposal** The code for `no_pagination` support should be deprecated, because no UI controls define it anymore. It should be safe to remove it. Related code: https://gitlab.com/gitlab-org/gitlab/blob/81f86be30e01994e01361e400deff5d06a5328de/lib/gitlab/git/blame_mode.rb#L23
