Comment 5 for bug 1942394

To get a sense of the scale despite mdevctl being so small in it's function here
the rust portion of the build-dependency tree. (Due to the way rust libs work some are from the same source - so two lists):

Maybe some of them are for dh-rust, maybe we need all of them. Since there is no full detection for built-using yet (that I'd know of) this is guessing from what I get when I run apt build-dep in an empty container.
