The other main part of the consultation covers vaping specifically, and here the government seems much more confident, at least in some areas.
On flavours, for example, while it does ask whether there should be any restrictions at all, the consultation is much more focused on determining exactly what form those restrictions should take (the options are allowing tobacco only; tobacco, mint and menthol; or all those plus fruit flavours). The consultation very much implies that restrictions are a given, and only their precise shape is up for discussion.
