AFAIK, there is only one difference: key_id must be int and key_name must be string. Is there any other practice limitations using key_id vs key_name?

You are correct that the only difference is the type (1 != ‘1’). Note that it impacts the ordering of results if you sort by key (as you would expect) – integers are sorted before strings.
