Question about XDG directories

[researcher2312]

How do you think XDG directories, such as $XDG_CONFIG_HOME should be set? Should those variables be set in the .zshrc file or in some other way? Also, if i need to set some environment variables, such as export CARGO_HOME="$XDG_DATA_HOME"/cargo, should it be also in the .zshrc?
