@stevengj since xsum_jll now requires julia v1.6 this should also require the same version, I think?

Why? The Xsum.jl code per se doesn't require Julia 1.6, only one of its dependencies does.

Because I think the package can't be effectively installed in Julia v1.5-. I'm going to let this pull request be merged, we can fix compat bounds afterwards if necessary.

If package A depends on package B, and package B requires Julia ≥ 1.x, should package A also explicitly list Julia ≥ 1.x in its Project.toml? Isn't taking the conjunction of the package requirements the responsibility of Pkg?

I guess the counter-argument is that if you can no longer test package A on Julia < 1.x, it is safer to require ≥ 1.x explicitly in A even if you think it would work for previous versions if not for B.
