There was substantial confusion around this, but I've done some archaeology.
Basically, this was changed back in r0.5.0 by MSC1304 and matrix-org/synapse#3397. Before that, it was indeed the case that state_default was 0 if there was no m.room.power_levels event, but that was confusing and a source of security holes, so we changed it.
matrix-org/matrix-spec-proposals#1656 changed the spec, but apparently overlooked the text in the description.
Reverts: #1478.
Fixes: #861.
* Mention that `state_default` can be zero by default.
* Changelog
* Update data/event-schemas/schema/m.room.power_levels.yaml
