/**
* rooms can claim parents via the m.space.parent state event.
* canonical determines whether this is the main parent for the space.
*
* To avoid abuse where a room admin falsely claims that a room is part of a space that it should not be,
* clients could ignore such m.space.parent events unless either
* (a) there is a corresponding m.space.child event in the claimed parent, or
* (b) the sender of the m.space.child event has a sufficient power-level to send such an m.space.child event in the parent.
* (It is not necessarily required that that user currently be a member of the parent room -
* only the m.room.power_levels event is inspected.)
* [Checking the power-level rather than requiring an actual m.space.child event in the parent allows for "secret" rooms (see below).]
