[Disclaimer: I've clicked through the slides, not watched the presentation] - yet your comment makes me feel you may expect too many changes, much too quickly.
You see, the opinion of a co-founder isn't necessarily the opinion of the entire project. Anyone is free to contribute whatever he/she feels like the project needs; whether it will be adopted may be an entire different matter. Core changes like these _will_ get quite of lot of discussion, likely because the rc system 'just works' and I would not expect it to be changed anytime soon by something that hasn't matured.
Note that this is just the expectation I have from working a few years within the FreeBSD project, so YMMV, etc.
