I've deleted my Gmail mailbox and Android works fine, any document share notifications go to the email address on the Google account.

If anything it's better without a Gmail mailbox because those notifications used to only go to my Gmail no matter what alternative email addresses I set, now they all go to my actual email address.

Only problem is I can never reopen the mailbox because the "Add Gmail to your Google account" screen has decided I've already used my mobile number before.
