We use Stripe for all money handling.

Sure!
No, an account is only required for donating or withdrawing money from your account. Any repo with a .bread.yml file can forward money.
Any not-yet-configured projects, invalid accounts, etc. will be skipped from donations until they're set up.
The money will remain in any configured project until at least one valid destination is configured. If the project's configuration is deleted without distributing the money, the money will be considered forefeit after a period (see the Terms of Service for more information).
