If we're talking about complex multicellularity (ontogeny resulting in
multicellular differentiated organs), it's also found in crown
heterokonts and fungi, and even in plants, the rhodophytes and
streptophytes developed it separately, and there are chlorophytes that
are arguably multicellular.
If I wanted a morphological synapomorphy, I'd go for gastrulation.
