What are the `name` and `app_id` fields in `ionic.project` used for?

Does anybody know what the name and app_id fields in ionic.project are used for?

I changed my app_id using ionic config set app_id #### and also changed my App name in config.xml <name> and never noticed any problems. Now I’m wondering if I can just delete these two values and finally have on less place where I have to look after them.
