I've been having a read through this discussion and my view is that each robot should be armed up in the safest way possible and what might be safe or practical for one robot may not be for another.

Take Maelstrom for example- if this rule about using a standard tool for gas was made compulsory then it would fall foul of this rule because the tool would have to pass through the wheel and gearbox which isn't very practical, safe or do-able.

However- the tool could still be used to turn on the bottle but not in the way intended- those who have seen how we arm Maelstrom will understand how.

I think that it might be an idea to introduce this rule for any new build though.
