It sounds like if there are really people who don't want drones to be able to warp (which would be a NEW limit), then perhaps two lines in settings.txt would be ideal:

Drones can be given move/warp orders := true/false
Drones can pass through warp points := true/false

Of course, if the new limit on warping were set to false, then the drones should not accept target or destination orders that aren't in the same system that they are.

Mac's questions:

Can fighters shoot down drones? Yes, as long as they have weapons that can hit them (no torps or missiles), and an appropriate strategy.

Do drones have formations? I don't think drones can be added to fleets, so no. The best you can do is launch them and target them so they move in a horde. This helps a fleet of ships to be able to just chew them up with beam weapons and PD.
