I dunno, I find it hard to imagine anyone other than director Robert Rodriguez and longtime producer (and former wife) Elizabeth Avellan having full control over the Spy Kids franchise: they own it. Netflix did not choose him, they made a monetary deal with him and are the distributors. He chose them.
His production company:

My one disappointment is that this is supposedly about "the children of the world's greatest secret agents" but I do not see Carmen and Juni anywhere in the cast! I wanted the new kids to be cousins and the children of the original Spy Kids sister-brother team. If Carmen and Juni were recast with different actors, that is just WRONG!!
