what do you think about using uint256 explicitly?

If we provide a setter, I would go with a private visibility for the heir and providing a getter as well. This will ensure that inheriting contracts can not modify the heir in another way than the one proposed.

we may want the same thing for heartbeatTimeout and timeOfDeath

Makes sense, but this is not something we're implementing in general in OZ. Eg. Ownable has:

do we want a heartbeat to be greater than 0?

What do you mean? Do you mean that we should check for newHeartbeatTimeout > 0?
If so, isn't that implied in the uint type?

2 things:
- addresses may be indexed?
- we should use
uint256here too
