just make sure, you don’t break backwards compatibility, i.e. the possibility to read old log files. Plus the fact that we inherit the gas change events from libdivecomputer (with their limit of only providing info about the gas rather than the cylinder). Maybe we can have semantics that an old style “gas change” event implies a disconnect of all previous cylinders and have special events (“enable gas”) for the rebreather use you intend.
