Not until quite late. The salient point is that Maitreyanatha, Asanga, and Vasubandhu all use the type 1 presentation which means they all were cittamatrins by gshan stong pa standards.
As an aside, I tend to think of all this ultimately as less about ontology, and more about practice and experience. I always come to the conclusion that conceptual mind cannot directly know reality, much less formulate some sort of framework describing it.
The issue has been, as always, whether post-Yogacara Madhyamakas like Bhavaviveka were justified in their critiques of Maitreyanatha, Asanga, and Vasubandhu.
It is clear that after the attacks of Bhavaviveka and so on on the Yogacara school, that there was a response which involved a) altering the Perfection of Wisdom in 25 and 18 thousand lines with the addition of the Maitreya chapter in order to b) provide justification of the reworking the three nature model.
Basically, we can identify three phases of Yogacara: the sutra period, original commentatator period, and the post-Madhyamaka response period.
What we observe in period two is trenchent attacks by Asanga in particular on the austerity of the perfection of wisdom vision and a concern that it lead to a form of annihilationism.
What we observe in period three is a revamping of Yogacara, recasting the three natures in terms of the two truths.
This latter phase represents a defeat for the Yogacara system in general, since the three natures are completely unnecessary given the presentation of two truths. However, late Yogacarin partisans managed to communicate their ideas to Tibet, and since the time of Dolbupa, centuries of followers of gshan stong have been seriously confused about what the actual teaching of Maitreyanatha, Asanga, and Vasubandhu might have been, especially as this has been conflated with the tathagatagarbha theory.
