It's not really fine and no organization should do that. The assumption that one email address = one person is too deeply embedded into the infrastructure. Tech firms mostly get this right. Consumer Google accounts are never reused for example. Yes it means the namespace becomes polluted over time and some people might have numbers at the end of their email address, and that's a pity, but compared to the pain of reallocating addresses it's not very important.
