wireless charging – does Sony have an Abbandon Qi project?

The high-end smartphones of the Sony brand are equipped with wireless charging systems (Qi), namely the Xperia XZ2 and XZ3 models.

None of the new Xperia 10, Xperia 5 models and the new flagship product, the Xperia 1, supports wireless charging.

Sony is in the Wireless Power Consortium, but not in the list of members of the steering group.

Does this mean that Sony has abandoned the wireless charging of its smartphones?
