I first started flying aircraft with zero/zero bang seats in 2002. At least as far back as that we have been replacing pins on the taxi back. Indeed in certain aircraft we would fully unstrap and have the canopy open.
Should there be a fire the safest thing may be to shut the aircraft down and climb out.
You may now be horrified to hear this but consider how many uncontained engine fires there have been on the ground in this period (none that I am aware of). There have been several rapid egresses though where having the seat safe will have speeded (is this a word?!) up the process and made it more safe.
There have been procedural changes since Sean's accident but I won't go into them here. Please don't shoot the messenger.
