Presumably to allow the valve components to be assembled inside (during manufacture) 🤔

Gas Bayonet Socket
• BS669-1• For use with bayonet type cooker hoseThis product should only be installed by a Gas Safe registered engineer.
I expect it will be how they assembled the fitting.
In theory they are designed to be disconnected and gas tight. Realistically though I would get it capped. IT IS NOT SOMETHING A NON GAS SAFE ENGINEER CAN DO.
Guidance Note 65 to regulation 6(3) of GSIUR states:
“When an appliance is disconnected and open-ended pipework is left, the pipework should always be left sealed with an appropriate fitting. A self-sealing coupling, e.g. on a cooker connection, does not need to be capped-off, except where there is a significant risk of interference (such as by a child). However, it should be checked that any disconnected coupling is not leaking gas (see paragraph 68), and any wall- mounted connector has been installed in the downward mounted position to prevent dirt or grit getting into the self-closing seal.”
