Yeah, I've seen how these things can be way more complicated than they might seem from the outside. I think this could potentially be very difficult, but I also think that the possible advantages could be enormous so it is worth doing as much evaluation of what we might actually be able to accomplish, even if it is initially more limited than we would hope for the future.
I think that makes sense. The scope of a fully functional and capable modular ABI system is probably massive, so it would be good to focus initially on what we will be able to extend with more features later, and what could actually start bringing in benefits for some use-cases.
