I'm going to try graduated density module but at least for the color correction I always had the problem that it just didn't look as good as it would have been using the white balance. But I guess I'm just missing the experience to do it. Anyway I didn't want to say that the approach of Lightroom is better than the one of darktable. Both have their advantages and disadvantages. Nonetheless I don't have any clue about how darktable works internally but wouldn't the following be possible? Just have multiple pipeline calls per image each having their own modules, module masks etc. At the end of each pipeline a new module "global mask" is added that just applies the usual mask feature to the whole image creating (semi-)transparent areas (ideally the first pipeline wouldn't have that). Afterwards the result of all pipelines are just overlayed into one result image. Using that way both (and even a combination of both) would be possible: Having a mask per module or multiple modules per mask without having to calculate the mask multiple times. A easy "half step" solution for that might also be to have multiple local copies (each with its own XMP file) that can be grouped into a single image in the lighttable view. That approach would only need to create the "global mask" module and the image merge. Of course you could not see the result in real time but it would be a step into that direction :-)
