Where exactly? The description in that PR is pretty self-contained, and links to [CategoricalArrays forces OpenSpecFun\_jll recompilation - #18 by tim.holy](https://discourse.julialang.org/t/categoricalarrays-forces-openspecfun-jll-recompilation/87759/18) and [Warning when conditionally loading "glue" module · Issue #65 · JuliaPackaging/Requires.jl · GitHub](https://github.com/JuliaPackaging/Requires.jl/issues/65). Which themselves transitively link to [Warning when conditionally loading "glue" module · Issue #1238 · JuliaLang/Pkg.jl · GitHub](https://github.com/JuliaLang/Pkg.jl/issues/1238) (closed as for Base), [Warning when conditionally loading "glue" module · Issue #32413 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/32413) (no follow-up), [Thoughts on how we can make Requires precompile friendly. · Issue #33 · JuliaPackaging/Requires.jl · GitHub](https://github.com/JuliaPackaging/Requires.jl/issues/33) (closed in favour of Discourse topic) and [Optional dependencies / Requires.jl](https://discourse.julialang.org/t/optional-dependencies-requires-jl/3294) (contains relevant discussion but out of date). Oh, and a Slack thread where I tested the ideas in Requires.jl#65 but didn’t get much engagement after mentioning they failed.

It would be ideal if we could avoid forking this discussion onto another thread and instead continue here/consolidate it into an existing issue.
