As discussed in https://orgmode.org/list/87v9hzzhrn....@gmail.com the proposal is to allow users to customize *all* speed keys, not just some of them through `org-speed-commands-user'.
By merging `org-speed-commands-default' and `org-speed-commands-user' into a single `org-speed-commands' option, we make this possible, but this change will ignore people's `org-speed-commands-user' config, so this is a breaking change. Do you think this change could be too sensitive for users? -- Bastien
