I deliberately didn't link to those patches in my OP as I wanted to know if it was possible/feasible at all (perhaps with some rework). I was pretty sure if I had, the discussion would've only been about that specific implementation. The functionality (ie having the possibility to run Waydroid) seems appealing (even ideal) to me, but (for myself) I didn't want to make it built-in and having it available as a loadable module seems like a great way to have both options in my (and other's) kernel. And a functionality which should be available upstream if at all.
