Does parentData only work on layout files?

[StokleyO]

I've been struggling for the past week to pass parentData to child routes when the data originates in a page.server.ts file. But when it originates in a layout.server.ts file, the parentData passes just fine. Is this how the parentData functionality was intended to be used or is there something I'm missing? Any help would be greatly appreciated

Yes, this is intended. Only layout data gets passed down to child pages.
