Might be worth putting that in quotes - for a moment it sounded like you getting out of your pram! ;-)
Point worth noting at this point in case you were not aware both John S and Ed who have responded to parts of this thread are CORGIs.
To address specific points in the above - yes many of them are technically correct as I understand it (but note I am not CORGI). You should leak test after remove or reinstatement. As a minimum this should be with a proper leak test spray, or preferably by doing a full pressure drop test with a manometer at the test point on the meter. Bayonet fittings are not intended for long term isolation and hence should be capped when not in use. Anti tilt device etc should be present as previously discussed.
In addition there are a bunch of regulations regarding appliances like cookers, especially wrt to the ventilation and air volume requirements. Clearances will also be specified by the manufacturer.
On a more practical level, whether it is right or wrong to disconnect a bayonet fitting yourself is a moot point, since you chances of getting a CORGI out to do just that are going to be slim.
