...therefore try to balance commercial and safety...
I hope that I never fly as a passenger with any such airline which is prepared to compromise safety on so-called 'commercial' grounds.
The decision to leave the gear out is predicated on knowing that a decision to leave the gear out or not is required.
True enough - if you don't know whether a tyre burst occurred during the take-off roll, then you won't know whether or not you should consider leaving the undercarriage extended.
