There's always the question, if you're putting a lot of effort into
making kernel-doc closer to an actual C parser, why not put all that
effort into using and adapting to, you know, an actual C parser?

Not speaking to the current effort but ... in the past, when I have
contemplated this (using, say, tree-sitter), the real problem is that
those parsers simply strip out the comments.  Kerneldoc without comments
... doesn't work very well.  If there were a parser without those
problems, and which could be made to do the right thing with all of our
weird macro usage, it would certainly be worth considering.
