@DevonHess: I ship a current busybox build in
KoboStuff.
Busybox being a multicall binary, it can easily be unbundled from there with a bit of manual labor.
(Under absolutely no circumstances should you actually *replace* the stock busybox binary, though. Among other potential issues, a fairly immediate one is that I don't build the init applet ^^. And even if I did, it's a potentially terrible idea, don't do it.).
(Speaking of, I am currently working on making said packaging slightly less painful, because shipping 2 full python setups is a tiny bit insane).
