It would be useful to provide an option to allow non-Union{Missing,T} columns in Dataset via an argument. Always automatically converting a vector into Union{Missing,T} often introduces additional allocations and hinders integration with other packages.
In addition, it would be beneficial if the copycols argument were supported in more functions, including insertcols!() and hcat().
