I'm planning to use Google Drive service account because my application will be using it to store Realtime API documents. These will be shortcut files. On help page it says:
Because it is not possible to access the Google Drive web user interface of a service account, it is not possible to purchase additional Google Drive storage for this type of accounts. For that reason you may prefer using a regular account instead of a service account.
I seen 5GB figure floating around. Should I be worried about it if I'm only creating shortcut files? Is this limitation imposed purposefully? If so, why?
