Speculation: legal liability ass covering. If they allow it and it ends up as the probable cause in a plane crash that kills x hundred people it's a major disaster and likely to lose everyone's involved jobs. If they continue with current policy it's a continued minor inconvenience that many people ignore anyway. Payoff matrix is pretty much locked on status quo for now, maybe it will soften to "up to the airline but we advise against it" at some point and some of the smaller airlines will differentiate by allowing it and after a couple years the dam will burst.
