The external Oxy service panel is an option on most Boeing a/c. On earlier
models (before 1980) this included crew & pax oxy, but as all newer a/c use
oxy generators for the pax oxy the panel is now only for crew oxy. I can
tell you that a lot of airlines (including QANTAS) do use this system for
filling the crew oxy bottle. As someone who is often required to fill up
crew Oxy bottles, I  can assure you that it is a lot easier to top up using
the external charging panel, then it is to remove, refill, & replace a
bottle. The risk of explosion is very small given that only persons given
the appropriate training, and using the correct procedure carry out this
