I mean, no? It's been documented for a while that a CRTC should only
have a single primary, so I'd say that the invalid assumption was that
it was possible to have multiple primary planes for a CRTC.
Documented where?
I did read the doc of "enum drm_plane_type" in <drm/drm_plane.h>, and
the DRM_PLANE_TYPE_PRIMARY describes my two planes, so I went with that.

Since it looks like you have two mutually exclusive planes, just
expose
one and be done with it?
