This is why I asked if the aircraft has oxygen generators or tanks feeding a ring loop system. If it is tanks of oxygen then I believe it can be shut off to save the oxygen and then turned on again later if needed. If it is individual chemical oxygen generators in each PSU then obviously once they have been activated then those seats will be without an oxygen supply later should it be needed, which would be a serious risk.

Even if there's still oxygen, normally the way that passengers are aware of the need to use an oxygen mask is that it falls down in front of them. I'm surprised that the flight wasn't required to divert.

As long as the mask isn’t pulled down then oxygen is not supplied, any masks that is pulled the oxygen can be switched off, once the masks have dropped down they can only be restored by an engineer.

Agreed, but BA hate diverting, the cost is enormous. There is an ongoing CAA investigation at the moment, I'm sure this occurrence will provide them with plenty to look at.

Also surprised this isn't a mandatory divert.
I wonder how many pax started the flow of oxygen and for how long it flowed before being switched off? How many minutes of O2 are on board in any case? Enough for a decompressed aircraft to get below FL100 (a few minutes) or enough for a smoke filled a/c to divert - couple of hours in some cases?

And the masks provide zero protection against smoke inhalation
You really do not want a fire onboard

Ah, well I've seen images of crew wearing masks during a fumes incident, so I assumed that would extend to drowsy pax with a cabin leak, but no?
Anyway, I remain surprised that the inadvertent deployment of a key safety feature, that can't be reversed, doesn't require a divert. Will be interesting to read the CAA report if it's made public.

A fume event and a slow decompression are different things.
