I just made a package for doing this here: [GitHub - MilesCranmer/DeprecateKeywords.jl: Macro for deprecating keyword parameters](https://github.com/MilesCranmer/DeprecateKeywords.jl)

Described in this thread: [Standard way to deprecate a keyword argument](https://discourse.julialang.org/t/standard-way-to-deprecate-a-keyword-argument/100534)

```julia
using DeprecateKeywords

@deprecate_kws function foo(;
    new_kw1=2,
    new_kw2=3,
    @deprecate(old_kw1, new_kw1),
    @deprecate(old_kw2, new_kw2)
)
    new_kw1 + new_kw2
end

```
