Unless Google has dramatically improved performance, this is not good for anything beyond toy examples. Apps Script seems to suffering from the NotLovedByImportantExec syndrome, hence the lack of serious development resources. Till about a few days ago, saving a script before running used to take 5 min or so. Plus you run the risk of getting the rug pulled out from under you when some big shot at Google decides that it 'distracts' from some $important 'core mission' and does not 'align well'.
