notmuch cli argument "sort=oldest-first" in .notmuch-config?

Question

Is it possible to add arguments notmuch takes to .notmuch-config file? Arguments like --sort=oldest-first would be really helpful if set by default to notmuch search command.

My workaround is to override it in .zshrc, by it would be great if there was support directly in notmuch project:

notmuch() {
    if [[ $1 == "search" ]]; then
      # remove "search" from "$@"
      shift 1
      command notmuch search --sort=oldest-first "$@"
    else
      command notmuch "$@"
    fi
}

I've tried notmuch config set search.sort oldest-first, but it didn't work.
