Calling packadd multiple times on FileType event#1

Thanks for a great add-on to minpac. I had my own little add-on to minpac that only did lazy loading for filetypes, but I plan to trash mine and use yours since I liked the extra config options you have. This is more of a question: Do you know if there is any performance penalty for calling `packadd` multiple times on the `FileType` event if the plugin is already loaded (for `type: opt` plugins)? https://github.com/bennyyip/plugpac.vim/blob/master/plugpac.vim#L48
