This kind of invalidate the pitch of Pi, the self-modifying harness. You can't use the Pi extensions I'm assuming...
Without a plan of your own for extensions this is comparing apples to oranges. My Pi startup time is dominated by loading extensions and skills, and I don't even have many to begin with!
(It seems like there is a pluging API judging by the Github repo. That wasn't linked in the comments by the time of my writing)
