> is there any resource/ way to figure out whether installing a package will cause a similar deprecation?

Not really. We need something like this: [Optionally warn if `update` cannot install latest version of a package · Issue #1655 · JuliaLang/Pkg.jl · GitHub](https://github.com/JuliaLang/Pkg.jl/issues/1655)
