Personally I'm under the impression that law should be scale-able, and there should not be a distinction between leasing a unit, and leasing a room. The landlord may want to disallow things when leasing a room, but it must be agreed upfront as a form of 'restrictive term'.
I reckon it's all about legal possession.
If you have legal possession of the premises, you can give or restrict access to those premises as you so desire.
Following that, my opinion is that you cannot gain possession (in its complete sense) of a room within a flat. IIRC, in cases of duplexes (ie. two separate living spaces within a single condo), the concept of whether possession of one living space within a larger unit is achievable, was based on whether entry/exit to the primary living areas were separated.
Lastly, if it's established that you cannot have legal possession of a room within a unit, then IMHO it's the room renter who should specifically INCLUDE into the room tenancy contract - those types of rights which are similar to those of someone who has legal possession of a unit. It should not be the other way around ie. assumed that those rights are already native to the room renter and only excluded if stated in the room tenancy contract.
So I reckon there's no need for the landlord to restrict rights which a room renter does not have. It's the room renter who has to seek to include additional rights into the tenancy agreement.
