5.3+

Description

There is nothing stopping you from using an invalid name for the Target DI attribute.

How to reproduce

public function __construct(#[Target('someLogger')] LoggerInterface $logger)

In the above example, autowiring is not configured for Psr\Log\LoggerInterface $someLogger, the default logger is injected. I can imagine a scenario where you have a service injected but after an upgrade, the name is no longer valid so it is silently swapped for the default.

Possible Solution

I think the Target name should be validated when building the container and an exception thrown if invalid.
