Comment:
Here's a list of desiderata (see [here](http://mirrors.mit.edu/sage/spkg/upstream), [here](https://www.sagemath.org/links-components.html) and [here](https://repology.org/projects/?search=&maintainer=&category=&inrepo=sagemath&notinrepo=void_x86_64&repos=&families=&repos_newest=&families_newest=)).
This Sage [ticket](https://trac.sagemath.org/ticket/27330) tracks spkg's.
It's useful to look at config options that Sage the distribution [uses.](https://git.sagemath.org/sage.git/tree/build/pkgs)
