[POLL] Breaking change: removing `org-speed-commands-user'

[Bastien]

As discussed in https://orgmode.org/list/87v9hzzhrn.fsf@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?
