No argument there.
But by "legacy" I was referring to when the BA designator was first used for all British Airways flights post-merger, i.e. 1974-ish onwards, not to BOAC/BEA flight numbers while they were separate airlines.
Some 40+ years later, the demarcation still holds - that's a fair old legacy.
