Unlike most other commands bang in :map! is not a modifier. :map! to :map is the same as :vmap to :map, just with different set of modes. It is listed in :h :map as a separate entity that is linked to :h mapmode-ic.

Note that technically it is a modifier: there is no :map! command. But this does not matter: unless you are a Vim developer you should treat this as a separate command.
