This was Maybe Anaconda? https://anaconda.org/anaconda/ncurses The approach in Sage is indeed very rare, but it's interesting that another similar situation is with another big Python computing stack (Anaconda), which was developed independently. In any case, it's worth mentioning Anaconda in the proposal. I didn't really think of Anaconda since it's not a single software application like Sage. As a self-contained packing system of course most packages included in Anaconda are of this nature. But of course Anaconda doesn't necessarily distribute *everything* it needs to work either. ncurses sort of makes sense to include since a buggy ncurses can be a real deal-breaker for UX. My favorite bugbear in Sage is its inclusion of patch. I wince every time I start a fresh build of Sage and it starts compiling patch. I'm sure there was a good reason for it, and it's very minor in the grand scheme of things, but I think points quite obvious for a need to have better control over what we can use from the system.
