Removal of email address unexpectedly removes all subscriptions
When removing a (non-primary) e-mail address, that is still used for subscriptions, all subscriptions for that email will be removed. Furthermore no unsubscription notices will be sent for the removal.
I expected that the removal of the old address would result in either: a) the change of the subscriptions to my primary address or b) a confirmation dialog warning me of the consequences. What actually happened is that I, without prior warning, got unsubscribed from all mailing lists that were still on the to be removed address.
In order to save others from making the same mistake, it would be nice if the form below at least had a warning about the consequences of deleting an email (a confirmation step would probably be even nicer).
Slightly related (as this happened during an attempt to switch many subscriptions to a new email at once): #435.
