Why launch these useless chips instead of a decent APU? It would be easy for them as they could simply make a desktop CPU with 8 Xe-cores. Lots of people in forums and youtube would like that. SFF builds with only iGPU have become much more common since a few years (Asrock Deskmini, thin clients from Dell, HP, Lenovo), and are much more flexible than those countless minimalistic 4x4 china-mini-pc boxes.
And it's not like Intel would loose GPU sales by making APUs... the train for that has long left. So why not make a competitor to AMDs 8000G desktop APU series?
