Perhaps another alternative:
Adding special "only if no other way possible" movecaps to acid/lava terrain borders - this would not change the buildcaps behaviour and would still enable players to attack - things to change would be:
* the movecaps calculation
* the routing function (and making a difference between route finding for road building and fugitives)
