It could be a similar issue as with electricians and electrical contacts: in principle there are far better alternatives to slotted, but because literally every electrician has a number of slotted screwdrivers anyway, slotted is cheap and changing the screw type for a product like a circuit breaker is just a huge hassle for everyone involved nobody bothers.

Edit: actually for circuit breakers the combo of slotted and pozidrive is becomming more common recently. i guess that doesn't work for small screws though.

    it is not dangerous in any way since it is just metal and metal oxides that do not mobilize at the temps you use for soldering. it is not recommended because the protective layer on most modern soldering irons is made from iron (not steel) and iron is softer than steel.
