I 100% assure you that everyone handling gmail errors and getting burned isn’t just tossing failures into a single bucket. There’s a zillion reasons mail can bounce and all of them are taken into account. This is a particular bounce code that signifies that an ESP shouldn’t send email again to this address.
Email service providers are HIGHLY incentivized to act 100% in accordance with the wishes of the system where the mailbox exists because it’s highly likely that acting in any way that’s considered abusive could get your emails landing in a spam folder.
Mail boxes cease to exist thousands of times a day at places I’ve worked previously. Employees leave all the time and people shutdown mailboxes, this is Google’s fuckup, nobody else’s.
