Description
We will likely have to be more careful than in JuliaDiff/ChainRulesTestUtils.jl#205 and JuliaDiff/ChainRules.jl#499, since there are some hot paths here we probably do want to specialize, but I suspect that there are still some gains to be had. https://timholy.github.io/SnoopCompile.jl/stable/pgdsgui/ might be helpful here.

Research direction
Start by comparing JuliaDiff/ChainRulesTestUtils.jl#205 and JuliaDiff/ChainRules.jl#499, then use the linked SnoopCompile.jl PGDS GUI to inspect specialization. The issue is complete when opportunities to reduce specialization are identified without removing specialization from important hot paths.
