I happen to watch a video from AP on dodging and burning. In it - he did mention that he is using wacom but he also confirmed that he pretty much use it for shapes creating. I will check github if there is a feature request at all.
And yes - there is one from quite a while back but still in the works.
The tablets were always too pricey for me. Only recently they fell within a more reasonable price. I guess it will take some time to have a better adoption and more enhanced support.
